Description

Technical Field

[0004] , ,

[0001] The present disclosure relates to the field of signal power amplification technology, and specifically to a power amplification circuit for similarity merging and cancellation.

Background Art

[0002] In a signal power amplification technology device, in terms of output power performance indicators, it is required that in the power amplification circuit, the output gain in the power amplification circuit has a gain linearity similar to Class A, Class AB, or Class AB, and the distortion signal in the output power satisfies the requirements of the power linearity ACPR (adjacent channel power ratio) value, and when the output power is rated, the operating efficiency is high. In recent years, as technologies for achieving that the power amplification circuit has a gain linearity of Class A or Class AB and satisfies the requirements of the operating efficiency with certain power linearity indicators, the existing technologies currently include feedforward technology, analog predistortion technology, digital-analog predistortion technology, digital predistortion technology, a hybrid technology of analog predistortion or digital-analog predistortion and feedforward, a technology where the amplifier in the feedforward is Doherty, and a feedforward cancellation merging technology.

[0003] Here, the analog predistortion technology, the analog-digital predistortion technology, and the digital predistortion technology all have the effect of canceling the distortion signal in the output power of the Class A, Class AB, or Doherty power amplification circuit similar to Class AB, and in particular, the efficiency after cancellation in cooperation with Doherty is high.

[0004] Analog pre-distortion technology, analog-digital pre-distortion technology, and digital pre-distortion technology cannot extend the gain-linear dynamic range of a Class C or Class C-like power amplifier circuit, nor can they extend the output gain-linear dynamic range of a Class C power amplifier circuit with a constant gain-linear dynamic range to a power dynamic range where the output main power is smaller.

[0005] A Doherty power amplifier circuit is formed by combining a Class C power amplifier with a Class A power amplifier, or a Class C power amplifier with a Class AB power amplifier, via an impedance matching network. It can achieve a gain-linear dynamic range similar to that of a Class A or Class AB power amplifier, and only with this linear dynamic range can distortion cancellation be performed by applying DPD (digital pre-distortion), APD (analog digital pre-distortion), or ADPD (analog digital pre-distortion). Since DPD, APD, and ADPD are all distortion signals in the main power signals of Class A and Class AB amplifiers, they cannot compensate for the gain-linear dynamic range of a Class C amplifier. Therefore, Class C amplifiers have high efficiency but poor linearity, while Class A and Class AB amplifiers have improved linearity but low efficiency. Feedforward amplifiers and ADPDs can improve not only linearity but also efficiency. APD and DPD + Doherty can improve not only linearity but also efficiency. In a feedforward amplifier, the main amplifier is a Doherty feedforward merger + canceller, or the gain extension range of the feedforward canceller of the Class C itself is limited. Therefore, if the extension range meets the requirements, the efficiency of the Class C decreases, and if the efficiency of the Class C is high, the extension range is insufficient.ADPD+feedforward or APD+feedforward is a configuration where the distortion signal in the distortion extraction circuit of the feedforward circuit does not contain a Class C distortion signal. This means that the achieved amplifier gain linearity cannot satisfy the range of Class A, Class AB, P1dB (1dB power compression point) or more than 30dB below it, or the amplifier in the feedforward circuit cannot satisfy this requirement. If the cancellation requirement of APD or ADPD is met to reach 45dBc, there is a certain requirement that the feedforward amplifier itself must reach 35dBc or more relative to linearity, which reduces the efficiency of the feedforward amplifier itself.

[0006] Analog pre-distortion technology, analog-digital pre-distortion technology, and digital pre-distortion technology provide very little or no compensation for the output distortion signal of a Class C power amplifier circuit with very low gain linearity, or the compensation for the output distortion signal of a Class C or Class C-like power amplifier circuit with gain linearity within a certain range becomes, as the range of gain linearity extends to lower output power, from a very small value to a value within half or one-third of the compensation value for the output distortion signal of a Class A or Class AB power amplifier circuit, at which point the efficiency of the Class C-like power amplifier circuit approaches that of the Class AB power amplifier circuit, and still does not satisfy the requirement that the gain of the power amplifier circuit is Class A, Class AB, or Class AB-like gain linearity.

[0007] While feedforward technology can satisfy the output linearity requirements of power amplifier circuits such as Class AB and Doherty Class, the overall operating efficiency of the machine after feedforward technology compensates for the output linearity requirements of the Doherty power amplifier circuit is significantly lower than the overall operating efficiency of the machine after DPD compensates for the output linearity requirements of the Doherty power amplifier circuit.

[0008] In the AP or APD feedforward technology, the pre-distortion circuit after the cooperative compensation of a Class C or similar power amplifier circuit extracts the pre-compensated portion and cancels out the distortion signal, and in the post-subcircuit realized by the feedforward cancel-out time delay circuit in the feedforward technology, the cancel-out distortion signal of the pre-subcircuit after the cooperative compensation is canceled out, because the pre-subcircuit is the same as analog pre-distortion technology or analog-digital pre-distortion technology and the cooperative compensation of a Class C or similar power amplifier circuit.

[0009] The collaboration between the various linearization techniques mentioned above and high-efficiency amplifier technologies is insufficient in all aspects; therefore, how to improve the efficiency and linearity of power amplifier circuits is a subject that deserves diligent research. [Overview of the Initiative] [Problems that the invention aims to solve]

[0010] The object of this disclosure is to provide a power amplifier circuit with similar merging and cancellation functions, specifically a power amplifier circuit equipped with similar merging and cancellation functions, which, under small signal conditions, can improve the linear ACPR value of the main power signal to 30-35 dBc or higher, similar to Class C, by extending the gain linearity of the main power signal of the branch-like input merging and main signal merging circuit, and can also improve the linear ACPR value of the main power signal to 40-45 dBc or higher, similar to Class C, by extending the gain linearity of the main power signal of the main circuit of the branch-like input merging and cancellation merging. [Means for solving the problem]

[0011] This disclosure proposes a technical solution to the above problems, specifically a power amplifier circuit for similar merging and canceling, in which the output terminals of a parallel circuit of main signal branch-like input merging and input canceling or a series circuit of main signal branch-like input merging and input canceling are connected to a main power amplifier circuit, thereby configuring a power amplifier circuit for similar merging and canceling that has the function of a merged main circuit of branch-like input merging and input canceling, in which the output terminals of the combined circuit of the main signal and branch-like input merging in the parallel circuit of main signal branch-like input merging and input canceling or the series circuit of main signal branch-like input merging and input canceling are connected to the input terminals of the main power amplifier circuit, thereby realizing a merged main circuit of branch-like input merging and main signal. In the main circuit of the branch-like input merge and input canceller of the aforementioned similar merge and canceller power amplifier circuit, the parallel circuit of the main signal branch-like input merge and input canceller is realized by connecting in parallel the analog input terminals of the two circuits, the main signal and branch-like input merge combination circuit and the branch-like input canceller circuit, or the analog input terminal of one of the two circuits and the digital input terminal of the other, or the digital input terminals of the two circuits and the output terminals of the two circuits, via a merge input shunt circuit or a merge digital input shunt circuit and a merge output merge circuit. It is constructed by connecting the analog input terminal and the digital input terminal of one circuit to the other, or the digital input terminals of the two circuits to the output terminals of the two circuits in parallel, or by connecting the input terminals of the two circuits of a combined circuit that merges branch-like input merging and input cancellation and the corresponding main signal time delay adjustment circuit for input merging or input cancellation, or by connecting the analog input terminal of one of the two circuits and the digital input terminal of the other to the output terminals of the two circuits in parallel, where the input terminal of the merge input shunt circuit or the digital input terminal of the merge digital input shunt circuit and the output terminal of the merge output merging circuit are the input terminals or digital input terminals and output terminals corresponding to the parallel circuit of main signal branch-like input merging and input cancellation. In the aforementioned power amplifier circuit for similar merging and canceling, in the merging main circuit for branch-like input merging and input canceling, the series circuit of the main signal branch-like input merging and input canceling is realized by connecting in series a combination circuit of the main signal and branch-like input merging and a combination circuit of the main signal and branch-like input canceling, where the input terminal and output terminal of the combination circuit of the main signal and branch-like input canceling are the corresponding input terminal and output terminal of the series circuit of the main signal branch-like input merging and input canceling, Here, among the parallel circuits of main signal branch-like input merging and input cancellation, only one can be used as a main signal time delay adjustment circuit for either input merging or input cancellation, and among the combined circuits of main signal and branch-like input merging or main signal and branch-like input cancellation, only one can be used as a main signal time delay adjustment circuit for either input merging or input cancellation. A combination circuit of a main signal and a branch-like input merge, or a combination circuit of a main signal and a branch-like input cancel, is realized by connecting in parallel the input terminals of two circuits, or the analog input terminal of one of the two circuits and the digital input terminal of the other, to the output terminals of the two circuits, via a branch-to-main-path merge or branch-to-main-path cancel input shunt circuit or a branch-to-main-path merge or branch-to-main-path cancel digital input shunt circuit and a branch-to-main-path merge or branch-to-main-path cancel output merge circuit. Alternatively, the combined circuit of branch-like input merging and input cancellation is realized by connecting in parallel the input terminals of the two circuits, or the digital input terminals of the two circuits, or the analog input terminal of one of the two circuits and the digital input terminal of the other, to the output terminals of the two circuits, via a branch-to-main-path merging or branch-to-main-path cancellation input shunt circuit or a branch-to-main-path merging or branch-to-main-path cancellation digital shunt circuit and a branch-to-main-path merging or branch-to-main-path cancellation output merging circuit. The branch-like input merge circuit outputs a distortion signal with input common-mode merge compensation, and is designed to compensate so that the gain-linear dynamic range of the main power signal output from the Class C main power amplifier circuit, which is smaller than the input merge synchronous power point, extends to main power signals with low output power levels. The branch-like input cancellation circuit outputs a pre-distortion signal having input inverse-phase similar cancellation, and is provided to have characteristics similar to a distortion signal that is larger than the input cancellation synchronization power point of a Class C main power signal whose gain linear dynamic range is extended compared to the main power signal of the branch-like input merge and the main signal merge main circuit. The characteristics of input merging and input cancellation at the output terminal of a merging main circuit, similar to branching paths, are as follows: In a main circuit that combines branch-like input mergers and main signals, at the input merge synchronous power point, and in a main circuit that combines branch-like input mergers and input cancellers, at the input canceller synchronous power point, and when the main power amplifier is a Class C power amplifier, the time delays are equal or nearly equal, the amplitudes are equal or nearly equal, the phases of the two circuits in the main circuit that combines branch-like input mergers and main signals are within the range of 0 to 45 degrees, and the phases of the main circuit that combines branch-like input mergers and input cancellers are opposite or nearly opposite, where, In a parallel circuit of main signal branch-like input merge and input canceller, or a series circuit of main signal branch-like input merge and input canceller that satisfies the above conditions, a distortion signal with input common-mode merge compensation output from the branch-like input merge circuit and a pre-distortion signal with input out-of-mode similar canceller output from the branch-like input canceller circuit are generated at the output terminal of the parallel circuit of main signal branch-like input merge and input canceller, or the series circuit of main signal branch-like input merge and input canceller, thereby realizing a merge-canceler-combined distortion signal. Here, among the merge-canceling composite distortion signals, the distortion signal of input common-mode merge compensation generated by the branch-like input merge circuit has the characteristic of compensating so that the gain-linear dynamic range of the main power signal, which is smaller than the input merge synchronous power point among the Class C main power signals output from the Class C main power amplifier circuit, extends to main power signals with low output power levels, at the output terminal of the branch-like input merge and main signal merge main circuit at a point equal to the input merge synchronous power point. When the delays are equal, the amplitudes are equal or nearly equal, and the phases of two of the circuits are within the range of 0 to 45 degrees, the gain-linear dynamic range of the distortion signal with common-mode merging compensation generated by the branch-like input merging circuit and the Class C main power signal output from the Class C main power amplifier circuit, which is smaller than the input merging synchronous power point, is compensated to extend to main power signals with lower output power levels, and the EVM (Error Vector Magnitude) value and gain fluctuation are improved within the gain-linear dynamic range of the signal that has already been extended to a smaller output main power, thereby improving the linear ACPR value of the Class C main power signal with an extended gain-linear dynamic range of the main power signal of the branch-like input merging and main signal merging main circuit to 30 to 35 dBc or higher. Here, if the linear ACPR value of a Class C main power signal, in which the gain linear dynamic range of the main power signal is extended at the output terminal of the main circuit that merges the branch-like input merge and the main signal, reaches 30-35 dBc or more, then the pre-distortion signal of the input inverse phase similar canceling generated by the branch-like input canceling circuit among the merged canceling combined distortion signals has characteristics similar to the distortion signal of a Class C main power signal in which the gain linear dynamic range of the main power signal of the main circuit that merges the branch-like input merge and the main signal is extended, and is greater than the input canceling synchronous power point. If, at the output terminal of the merging main circuit of the branch-like input merge and input canceller, the time delays at the same point as the input canceller synchronization power point are equal or nearly equal, the amplitudes are equal or nearly equal, and the phases are opposite or nearly opposite, then an inverse phase similar canceller is achieved between the pre-distortion signal with inverse phase similar canceller generated by the branch-like input canceller circuit and the distortion signal of the Class C main power signal, which has an extended gain linear dynamic range for the main power signal of the merging main circuit of the branch-like input merge and main signal, and which is greater than the input canceller synchronization power point. The linear ACPR value of the Class C main power signal, which has an extended gain linear dynamic range, is increased to 40-45 dBC or higher, or the linear ACPR value of the main power signal, which has an extended gain linear dynamic range, is increased to 40-45 dBC or higher, and the linear ACPR value of the main power signal, which has an extended gain linear dynamic range, is increased gain linear dynamic range This extends the gain linear dynamic range of the output main power signal to Class C, further extends it to smaller output main power signals, and improves the EVM value and gain fluctuations within the gain linear dynamic range of the signal already extended to smaller output main power, thereby extending the gain linear dynamic range of the main power signal of the merging main circuit of branch-like input merging and input cancellation, or further improves the linear ACPR value of the extended Class C main power signal to 40-45 dBC or higher, and also improves the overall mechanical efficiency of the power amplification circuit of similar merging and cancellation. Alternatively, a power amplifier circuit for similar merging and canceling, which functions as a merging main circuit for branch-like input merging and input canceling and a branch-like output canceling circuit, can be realized by connecting in parallel the analog input terminals of the two circuits, the digital input terminals of the two circuits, or the analog input terminal of one of the two circuits and the digital input terminal of the other, to the output terminals of the two circuits via a merging input shunt circuit or a merging digital input shunt circuit and a merging output coupling circuit. Here, among the branch-like input merging cancellation and branch-like output cancellation merging main circuit circuits, only one can be used as the main signal time delay adjustment circuit for input merging or input cancellation. Here, the branch-like output cancellation circuit generates a distortion signal with output inverse phase similar cancellation at the output terminal, and has characteristics similar to a distortion signal whose gain linear dynamic range of the main power signal of the branch-like input merging and input cancellation merging main circuit is extended to a Class C main power signal with an extended output cancellation synchronous power point. The output cancellation characteristics at the output terminal of the merging main circuit for branch-like input merging cancellation and branch-like output cancellation are as follows: When the linear ACPR value of a Class C main power signal with an extended gain linear dynamic range at the output terminal of a merged main circuit of branch-like input merging and input cancellation reaches 40-45 dBC or higher, and the time delays at the output cancellation synchronization power points in the merged main circuit of branch-like input merging cancellation and branch-like output cancellation are equal or nearly equal, the amplitudes are equal or nearly equal, and the phases are opposite or nearly opposite, then a distortion signal with output inverse phase similar cancellation characteristics generated by a branch-like output cancellation circuit is considered to have branch-like input merging and input cancellation characteristics. The main power signal output from the merged main circuit of force cancellation has a gain-linear dynamic range that is similar to a distortion signal that is larger than the output cancellation synchronous power point of a Class C main power signal with an extended gain-linear dynamic range. This results in a distortion signal having an output inverse phase synchronous cancellation generated by the branch-like output cancellation circuit at the output terminal of the merged main circuit of branch-like input merge cancellation and branch-like output cancellation, and an output phase inverse phase synchronous cancellation of a Class C main power signal with an extended gain-linear dynamic range that is similar to a distortion signal that is larger than the output phase cancellation synchronous power point of a Class C main power signal with an extended gain-linear dynamic range that is similar to a main power signal output from the merged main circuit of main-like input merge cancellation and input cancellation. Distortion signals greater than the synchronous power point are canceled out, and the main power signal output from the merged main circuit of the branch-like input merge and branch-like output merge is further expanded, improving the linear ACPR value of the Class C main power signal to 50-55 dBC or higher, or the distortion signal with output inverse phase synchronous canceling generated by the branch-like output canceling circuit and the output canceling of the Class C main power signal whose gain linear dynamic range of the main power signal output from the merged main circuit of the main-like input merge and input canceling is expanded Cancellation with distortion signals larger than the synchronous power point is achieved, and the gain linear dynamic range of the main power signal of the merged main circuit of the branch-like input merge and input cancelling is extended by the reverse compensation characteristics of the Class C main power signal, which has an extended gain linear dynamic range of the main power signal, is further extended to have a smaller output main power range, and the EVM value and gain fluctuation are improved within the further extended gain linear dynamic range.The main power signal output from the merging main circuit of the branch-like input merging cancellation and branch-output cancellation further improves the linear ACPR value of the extended Class C main power signal to 50-55 dBC or higher, and also improves the overall efficiency of the machine. Alternatively, by connecting the main power output terminal of the feedforward distortion extraction circuit of the branch-like input merging and input cancellation merging main circuit to the main power input terminal of the main circuit feedforward output cancellation circuit, and connecting the distortion output terminal of the feedforward distortion extraction circuit of the branch-like input merging and input cancellation merging main circuit to the distortion input terminal of the main circuit feedforward output cancellation circuit, a power amplification circuit for similar merging and cancellation that functions as a circuit in which branch-like input merging cancellation and feedforward output cancellation are connected in series is realized. Here, in a series circuit of branch-like input merge canceller and feedforward output canceller, the main circuit feedforward merge canceller circuit is realized from the input terminal of the main circuit of the main circuit feedforward input coupling circuit, through the feedforward distortion adjustment power amplifier circuit connected via the feedforward main circuit time delay circuit and the output terminal of the feedforward distortion output merger circuit, to the output terminal of the feedforward canceller coupling circuit. The characteristics of the same type of cancellation at the output terminal of a series circuit of branch-like input-merging cancellation and feedforward output cancellation are as follows: When the gain-linear dynamic range of the main power signal is extended at the output terminal of the merged main circuit of branch-like input-merging and input cancellation, and the main power linear ACPR of Class C reaches 40-45 dBC or higher, then at the output terminal of the series circuit of branch-like input-merging cancellation and feedforward output cancellation, the time delays at the feedforward cancellation synchronization power points are equal or nearly equal, the amplitudes are equal or nearly equal, and the phases are opposite or nearly opposite. The distortion signal among the Class C main power signals, in which the gain linear dynamic range of the main power signal output from the merged main circuit of, is extended. When the distortion signal is of the same type as the main signal, and at the output terminal of the main path feedforward merge canceller circuit, the time delay at the feedforward canceller synchronization power point is equal or nearly equal, the amplitude is equal or nearly equal, and the phase is opposite or nearly opposite, the distortion signal of the same type among the distortion signals of the Class C main power signals, which have an expanded gain linear dynamic range of the main power signals output from the merge main path circuit of branch-like input merge and input canceller, is canceled out, and the gain linear dynamic range of the Class C output main power signal, which has an expanded gain linear dynamic range of the main power signal, is further expanded to reach the gain linear dynamic range of the Class AB output main power, and the EVM value and gain fluctuation are improved within the already expanded gain linear dynamic range, thereby improving the total linear dynamic range of the Class C main power signals output from the circuit in which branch-like input merge canceller and feedforward output canceller are connected in series, until the linear ACPR value of the Class AB output power signal reaches 50-55 dBC or higher, and the overall efficiency of the machine is improved.

[0012] In one embodiment, by connecting the output terminals of a parallel circuit of main signal branch-like input merging and input cancellation, or a series circuit of main signal branch-like input merging and input cancellation, to a main line power amplifier circuit, a power amplifier circuit for similar merging and cancellation that functions as a merged main line circuit of branch-like input merging and input cancellation is configured. In this embodiment, the output terminals of the combined circuit of the main signal and branch-like input merging in the parallel circuit of main signal branch-like input merging and input cancellation, or the series circuit of main signal branch-like input merging and input cancellation, are connected to the input terminals of the main line power amplifier circuit, thereby realizing a merged main line circuit of branch-like input merging and the main signal. Here, the branch-like input merge circuit is used to output a distortion signal with input common-mode merge compensation, and has the characteristic of compensating so that the gain-linear dynamic range of the main power signal among the Class C main power signals output from the Class C main power amplifier circuit that is smaller than the input merge synchronous power point extends to main power signals with low output power levels. Here, the branch-like input cancellation circuit is used to output a pre-distortion signal having input inverse-phase similar cancellation, and has characteristics similar to a distortion signal whose gain linear dynamic range is greater than the input cancellation synchronous power point of a Class C main power signal whose main power signal of the branch-like input merge and main signal merge main circuit is extended. The characteristics of input merging and input cancellation at the output terminal of a main circuit combining branch-like input merging and input cancellation are as follows: at the input merging synchronous power point in the main circuit combining branch-like input merging and main signal, and at the input cancellation synchronous power point in the main circuit combining branch-like input merging and input cancellation, and when the main power amplifier is a Class C power amplifier, the time delays are equal or nearly equal, the amplitudes are equal or nearly equal, and the phases of the two circuits in the main circuit combining branch-like input merging and main signal are within the range of 0 to 45 degrees, and the main circuit combining branch-like input merging and input cancellation When the phases of the circuits are opposite or nearly opposite, in a parallel circuit of a main signal branch-like input merge and input canceller, or a series circuit of a main signal branch-like input merge and input canceller that satisfies the above conditions, a distortion signal with input common-phase merge compensation output from the branch-like input merge circuit and a pre-distortion signal with input out-of-phase similar canceller output from the branch-like input canceller circuit are generated at the output terminal of the parallel circuit of the main signal branch-like input merge and input canceller, or the series circuit of the main signal branch-like input merge and input canceller, forming a merge-canceling composite distortion signal. Here, if the distortion signal of the input common-mode merging compensation, generated by the branch-like input merging circuit, among the merging cancel-combined distortion signals, has the characteristic that the gain-linear dynamic range of the main power signal smaller than the input merging synchronous power point among the Class C main power signals output by the compensation class C main power amplifier circuit extends to main power signals with low output power levels, then at the output terminal of the branch-like input merging and main signal merging main circuit, at the point equal to the input merging synchronous power point, the time delays are equal, the amplitudes are equal or approximately equal, and the phases of the two circuits are within the range of 0 to 45 degrees, then branch This system compensates for distortion signals with common-mode merging compensation generated by a branch-like input merging circuit, and for Class C main power signals output from a Class C main-circuit power amplifier circuit, by extending the gain-linear dynamic range of main power signals smaller than the input merging synchronous power point to main power signals with lower output power levels. It also improves the EVM value and gain fluctuations within the gain-linear dynamic range of signals already extended to smaller output main powers, thereby increasing the linear ACPR value of the Class C main power signal with an extended gain-linear dynamic range of the main power signal of the branch-like input merging and main signal merging main-circuit circuit to 30-35 dBc or higher. Here, if the linear ACPR value of a Class C main power signal, in which the gain linear dynamic range of the main power signal is extended at the output terminal of the main circuit that merges the branch-like input merge and the main signal, reaches 30-35 dBc or more, then the pre-distortion signal of the input inverse phase similar canceling generated by the branch-like input canceling circuit among the merged canceling combined distortion signals has characteristics similar to the distortion signal of a Class C main power signal in which the gain linear dynamic range of the main power signal of the main circuit that merges the branch-like input merge and the main signal is extended, and is greater than the input canceling synchronous power point. If, at the output terminal of the merging main circuit of the branch-like input merge and input canceller, the time delays at the same point as the input canceller synchronization power point are equal or nearly equal, the amplitudes are equal or nearly equal, and the phases are opposite or nearly opposite, then an inverse phase similar canceller is achieved between the pre-distortion signal with inverse phase similar canceller generated by the branch-like input canceller circuit and the distortion signal of the Class C main power signal, which has an extended gain linear dynamic range for the main power signal of the merging main circuit of the branch-like input merge and main signal, and is greater than the input canceller synchronization power point. The linear ACPR value of the Class C main power signal, which has an extended gain linear dynamic range, is increased to 40-45 dBC or higher, or an inverse phase similar cancellation is achieved between a pre-distortion signal with inverse phase similar cancellation generated by a branch-like input cancellation circuit and a distortion signal that is larger than the input cancellation synchronization power point of the Class C main power signal, which has an extended gain linear dynamic range, of the main power signal of the branch-like input merging and main signal merging main circuit, and the gain linear dynamic range of the main power signal is The gain linear dynamic range of the output main power signal of Class C is extended to the gain linear dynamic range of the output main power signal, and further extended to smaller output main power signals. Furthermore, the EVM value and gain fluctuations are improved within the gain linear dynamic range of the signal already extended to smaller output main power signals, thereby extending the gain linear dynamic range of the main power signal of the merging main circuit of branch-like input merging and input cancellation, or further improving the linear ACPR value of the extended Class C main power signal to 40-45 dBC or higher. In addition, the overall mechanical efficiency of the power amplifier circuit of similar merging and cancellation is improved.

[0013] In one embodiment, the main power amplifier circuit in a merging main circuit with branch-like input merging and input cancellation is a Class C power amplifier circuit, and is composed of a single-channel Class C power amplifier circuit, or is composed of at least one Class C multi-channel power amplifier circuit that passes through merging or impedance conversion network merging.

[0014] In one embodiment, in a merging main circuit of branch-like input merge and input cancellation, where the parallel circuit of the main signal branch-like input merge and input cancellation is a merge input shunt circuit or a merge digital input shunt circuit and a merge output merge circuit, a combination circuit of the main signal and branch-like input merge, a distortion extraction adjustment amplifier circuit of the analog distortion of the main signal and branch-like input merge, or an analog digital distortion circuit of the branch-like input merge, or a digital distortion circuit of the branch-like input merge, and branch-like input It is configured by connecting the analog input terminals of the two circuits of the force cancellation circuit, or the analog input terminal of one of the two circuits and the digital input terminal of the other, or the digital input terminals of the two circuits and the output terminals of the two circuits in parallel, or a combination circuit of the main signal and the branch-like input cancellation, which is a combination circuit of the main signal and the analog pre-distortion of the branch-like input cancellation, or the branch-like input merging of the branch-like input cancellation and the main A signal merging auxiliary circuit is configured by connecting in parallel the analog input terminals of two circuits, or the analog input terminal of one of the two circuits and the digital input terminal of the other, or the digital input terminals of the two circuits and the output terminals of the two circuits, or a merge input shunt circuit or a merge digital input shunt circuit and a merge output merging circuit. The circuit is constructed by connecting in parallel the input terminals of two circuits, a combined circuit that merges branch-like input merging and input cancellation and a main signal time delay adjustment circuit for the corresponding input merging or input cancellation, or the analog input terminal of one of the two circuits and the digital input terminal of the other, with the output terminals of the two circuits, where the input terminal of the merge input shunt circuit or the digital input terminal of the merge digital input shunt circuit, and the output terminal of the merge output merging circuit are the input terminals or digital input terminals and output terminals corresponding to the parallel circuit of main signal branch-like input merging and input cancellation. Here, among the parallel circuits of main signal branch-like input merging and input cancellation, only one can be used as a main signal time delay adjustment circuit for either input merging or input cancellation, and among the combined circuits of main signal and branch-like input merging or main signal and branch-like input cancellation, only one can be used as a main signal time delay adjustment circuit for either input merging or input cancellation. The cancellation characteristics of the combined distortion signal of the main signal, which is a combined main circuit of a branch-like input merge and input canceller, are as follows: at the input merge synchronization power point in the branch-like input merge and main signal combined main circuit, and at the input canceller synchronization power point in the branch-like input merge and input canceller combined main circuit, and when the main power amplifier is a Class C power amplifier, the time delays are equal or approximately equal, and the amplitudes are equal or approximately equal, and the two circuits in the branch-like input merge and main signal combined main circuit When the phase is within the range of 0 to 45 degrees, and the phases of the branch-like input merge and input cancel-out main circuit are opposite or nearly opposite, in a parallel circuit of a main signal branch-like input merge and input cancel-out that satisfies the above conditions, a distortion signal with input common-phase merge compensation output from the branch-like input merge circuit and a pre-distortion signal with input out-of-phase similar cancel-out output from the branch-like input cancel-out circuit are generated at the output terminal of the parallel circuit of the main signal branch-like input merge and input cancel-out, forming a merge-canceling composite distortion signal. Here, among the merge cancellation combined distortion signals, the distortion signal of input common-mode merge compensation generated by the branch-like input merge circuit has the characteristic of compensating so that the gain-linear dynamic range of the main power signal, which is smaller than the input merge synchronous power point among the Class C main power signals output from the Class C main power amplifier circuit, extends to main power signals with low output power levels. Here, in the merged cancel-and-combined distortion signal, the pre-distortion signal of input inverse phase similar cancel-and-combination generated by the branch-like input cancel-and-combination circuit has characteristics similar to a distortion signal that is greater than the input cancel-and-combination synchronous power point of a Class C main power signal whose gain linear dynamic range is extended, resulting from the merged main circuit of the branch-like input merge and the main signal.

[0026] In one embodiment, an ET (Envelope Tracking) circuit is connected to an ET power amplifier circuit that performs similar merging and cancellation. Here, the ET circuit is configured such that the input terminals of the envelope tracking control circuit and the input terminals of the ET main signal adjustment time delay circuit are each connected to the two output terminals of the ET shunt circuit. The envelope tracking control circuit is configured such that the output terminal of the envelope tracking signal processing circuit is connected to the envelope input terminal of the control power supply circuit. Here, the input terminal of the ET input shunt circuit, the power supply output terminals of the control power supply circuit with multiple different voltages, and the power supply input terminal, and the main signal output terminal of the ET main signal adjustment time delay circuit are the input terminal and power supply output terminal, and the power supply input terminal and main signal output terminal, respectively, of the ET circuit.

In the aforementioned ET power amplifier circuit for similar merging and cancellation, the ET control power supply and power characteristics of the merging main circuit power amplifier circuit for branch-path similar merging input cancellation are that, based on segment selection of the envelope tracking signal and the relationship between the drain voltage and output power, the corresponding main power is reached by different drain voltage combinations in the similar merging and cancellation power amplifier circuit corresponding to each segment region of the envelope tracking signal.

(Example 2) As shown in Figure 2, a specific embodiment of Example 2 of this disclosure is: The objective is to provide a power amplifier circuit for similar merging and canceling inputs, wherein the output terminal of a parallel-connected circuit of a main signal branch-like input merging and canceling inputs is connected to a main power amplifier circuit, thereby forming a merging main circuit of branch-like input merging and input canceling inputs.

[0045] Here, the parallel circuit of the main signal branch-like input merge and cancel is constructed by connecting in parallel the input terminals and output terminals of two circuits: the analog-digital distortion circuit of the branch-like input merge and the distortion extraction adjustment amplifier circuit of the auxiliary circuit of the branch-like input canceller, via a merge input shunt circuit and a merge output merge circuit. Here, the input terminal of the merge input shunt circuit and the output terminal of the merge output merge circuit are the input terminal and output terminal corresponding to the parallel circuit of the main signal branch-like input merge and cancel.

[0046] Here, the analog-digital pre-distortion circuit for the branch-like input merge is configured such that an analog-digital pre-distortion circuit, which generates an input common-mode compensated distortion signal and compensates for the Class C main power signal output from the Class C main power amplifier circuit such that the gain-linear dynamic range of the main power signal smaller than the input merge synchronous power point is extended to the output main power signal, is connected to the input terminal of the low-power input merge analog power amplifier circuit via the output terminal of the input merge digital-to-analog conversion circuit.

[0052] Here, the merge output merging circuit and the input cancel-distortion output merging circuit are composed of a merging circuit, a coupling circuit, or other circuit that realizes the merging function, and satisfy the power capacity requirements and the requirement that no new distortion is generated in the corresponding circuit.

[0053] Here, the input cancellation main signal adjustment power amplifier circuit is configured by connecting the main signal power amplifier circuit in series to an adjustment circuit formed by connecting an amplitude modulation circuit and a phase modulation circuit in series, and satisfies the requirements for the main signal power capacity in the corresponding circuit and the requirement that no new distortion is generated.

[0054] Here, the input cancellation distortion adjustment power amplifier circuit is configured by connecting a distortion signal power amplifier circuit in series to an adjustment circuit formed by connecting an amplitude modulation circuit and a phase modulation circuit in series, and satisfies the power capacity requirements corresponding to the corresponding distortion signal of the above-mentioned corresponding circuit, and the requirement that no new distortion is generated.

[0055] Here, the input cancellation coupling feedback adjustment circuit and the input merging coupling feedback adjustment circuit are configured by connecting the coupled output terminal of the feedback coupling circuit to a feedback signal adjustment power amplifier circuit, where the feedback signal adjustment power amplifier circuit is configured by connecting an amplitude modulation circuit to the feedback signal power amplifier circuit, or is configured from an amplitude modulation circuit.

[0056] Here, the main power amplifier circuit in the branch-like input merge and input cancellation merge main circuit is a Class C main power amplifier circuit and consists of a single-channel power amplifier circuit, or a multi-channel power amplifier circuit is formed by merge or by the merge of impedance transformation networks. Here, the main power amplifier circuit is a single-stage or multi-stage power amplifier circuit.

[0057] The beneficial effect of this second embodiment is that the merging and canceling characteristics at the output terminal of the merging main circuit of the branch-like input merging and input canceling are as follows. In a main circuit that combines branch-like input mergers and main signals, at the input merger synchronous power point, and in a main circuit that combines branch-like input mergers and main signals, at the input canceller synchronous power point, the time delays are equal or nearly equal, the amplitudes are equal or nearly equal, the phases of the two circuits in the main circuit that combines branch-like input mergers and main signals are within the range of 0 to 45 degrees, and the phases of the main circuit that combines branch-like input mergers and main signals are opposite or nearly opposite, in a parallel circuit of main signal branch-like input mergers and cancellers that satisfies the above conditions, a distortion signal with input common-mode merge compensation output from the branch-like input merger circuit and a pre-distortion signal with input inverse-mode similar canceller output from the branch-like input canceller circuit are generated at the output terminal of the parallel circuit of main signal branch-like input mergers and cancellers, forming a merger canceller composite distortion signal.

[0058] Here, if the distortion signal of the input common-mode merging compensation, generated by the branch-like input merging circuit, among the merging cancel-combined distortion signals, has the characteristic that the gain-linear dynamic range of the main power signal smaller than the input merging synchronous power point among the Class C main power signals output by the compensation class C main power amplifier circuit extends to main power signals with low output power levels, then at the output terminal of the branch-like input merging and main signal merging main circuit in the branch-like input merging and input cancel-combining merging main circuit, the time delay of the point equal to the input merging synchronous power point is equal, the amplitude is equal or approximately equal, and the phase of two of these circuits is within the range of 0 to 45 degrees, then This system compensates for distortion signals with common-mode merging compensation generated by branch-like input merging circuits, and for main power signals of Class C output from a Class C main-circuit power amplifier circuit that are smaller than the input merging synchronous power point. The gain linear dynamic range of these main power signals extends to main power signals with lower output power levels, and improves the EVM value and gain fluctuations within the gain linear dynamic range of signals that have already been extended to smaller output main powers. This improves the linear ACPR value of the Class C main power signal, whose gain linear dynamic range has been extended, to 30-35 dBc or higher.

[0059] Here, if the branch-like input-merging main circuit reaches an extended range in the linear dynamic range of the Class C main power signal gain, and the linear ACPR value of the output Class C main power signal is 30-35 dBc or higher, and the pre-distortion signal of the input inverse phase similar cancellation generated by the branch-like input cancellation circuit among the merged cancellation combined distortion signals has characteristics similar to the distortion signal of the Class C main power signal whose linear dynamic range of the main power signal of the branch-like input-merging and main signal merged main circuit has been extended, then the branch-like input-merging and input cancellation merged main circuit At the output terminal, if the time delay at the same point as the input cancel-synchronous power point is equal or nearly equal, the amplitude is equal or nearly equal, and the phase is opposite or nearly opposite, then an inverse phase-like cancel-out is achieved between the pre-distortion signal with inverse phase-like cancel-out generated by the branch-like input cancel-out circuit and the distortion signal of the Class C main power signal, which has an expanded gain linear dynamic range, and is greater than the input cancel-synchronous power point. This improves the linear ACPR value of the Class C main power signal output from the branch-like input cancel-out and input cancel-out main circuit to 40-45 dBC or higher. Alternatively, inverse phase similar cancellation is achieved between a pre-distortion signal with inverse phase similar cancellation generated by a branch-like input cancellation circuit and a distortion signal greater than the input cancellation synchronous power point among the Class C main power signals whose gain linear dynamic range has been extended for the main power signal of the branch-like input merging and main signal merged main circuit. Furthermore, the EVM value and gain fluctuation are improved within the gain linear dynamic range of the output main power signal, which extends the gain linear dynamic range of the Class C output main power signal to a smaller range, and within the gain linear dynamic range of the signal that has already been extended to a smaller output main power. This improves the linear ACPR value of the Class C main power signal whose gain linear dynamic range has been extended for the main power signal of the branch-like input merging and input cancellation merged main circuit to 40-45 dBC or higher. In addition, the higher ACPR value improves the overall mechanical efficiency of the similar merging and cancellation power amplifier circuit.

[0060] Here, the degree of similarity and synchronization accuracy between the pre-distortion signal of input inverse phase similar cancellation generated by the branch-like input cancellation circuit and the distortion signal of a Class C main power signal with an expanded gain linear dynamic range, which is greater than the input cancellation synchronization power point, is determined by the degree of similarity and synchronization accuracy between the pre-distortion signal with inverse phase similar cancellation generated by the branch-like input cancellation circuit and the distortion signal of a Class C main power signal with an expanded gain linear dynamic range, which is greater than the input cancellation synchronization power point, which is greater than the input cancellation synchronization power point, which is greater than the input cancellation similar cancellation generated by the branch-like input cancellation circuit. (Example 3) As shown in Figure 3, a specific embodiment of Example 3 of this disclosure is: The objective is to provide a power amplifier circuit for similar merging and canceling, wherein the output terminal of a series circuit of a main signal branch-like input merging and input canceling is connected to a main line power amplifier circuit, the output terminal of the main line power amplifier circuit is connected to the input terminal of a coupling feedback adjustment circuit for input canceling, and the coupled output terminal of the series circuit of a main signal branch-like input merging and input canceling is connected to the coupled input terminal of a coupling feedback adjustment circuit for input canceling, thereby forming a merging main line circuit of branch-like input merging and input canceling.

[0061] Here, the system is composed of a series connection of a main signal branch-like input merge and cancellation series circuit, a combination circuit of the main signal and branch-like input merge, and a digital pre-distortion circuit for branch-like input cancellation.

The output terminal of the branch line input merging coupled output load circuit is the output terminal of the signal extraction circuit of the analog pre-distortion of the branch line-like input merging.

[0072] Here, regarding the analog distortion circuit for a branch-like input merge, the analog distortion circuit for a branch-like input merge formed by a low-power branch-like power amplifier circuit or a branch-like feedforward power amplifier circuit for the input merge generates a distortion signal for input common-mode merge compensation and has the function of compensating so that the gain-linear dynamic range of the main power signal, which is smaller than the input merge synchronous power point among the Class C main power signals output from the Class C main power amplifier circuit, is extended to the output main power signal which is smaller.

This achieves compensation such that the gain linear dynamic range of the distortion signal with common-mode merging compensation generated by the branch-like input merging circuit and the Class C main power signal output from the Class C main power amplifier circuit, which is smaller than the input merging synchronous power point, is extended to main power signals with lower output power levels, and the EVM value and gain fluctuation are improved within the gain linear dynamic range of the signal that has already been extended to a smaller output main power, thereby improving the linear ACPR value of the Class C main power signal with an extended gain linear dynamic range of the main power signal of the merging main circuit of the branch-like input merging and the main signal to 30-35 dBc or higher. Here, if the linear ACPR value of a Class C main power signal, in which the gain linear dynamic range of the main power signal is extended at the output terminal of the main circuit that merges the branch-like input merge and the main signal, reaches 30 to 35 dBc or more, then the pre-distortion signal of the input inverse phase similar canceling generated by the branch-like input canceling circuit among the merged canceling combined distortion signals has characteristics similar to the distortion signal of a Class C main power signal in which the gain linear dynamic range of the main power signal of the main circuit that merges the branch-like input merge and the main signal is extended, and is greater than the input canceling synchronous power point. If, at the output terminal of the merging main circuit of the branch-like input merge and input canceller, the time delays at the same point as the input canceller synchronization power point are equal or nearly equal, the amplitudes are equal or nearly equal, and the phases are opposite or nearly opposite, then an inverse phase similar canceller is achieved between the pre-distortion signal with inverse phase similar canceller generated by the branch-like input canceller circuit and the distortion signal of the Class C main power signal, which has an extended gain linear dynamic range for the main power signal of the merging main circuit of the branch-like input merge and main signal, and is greater than the input canceller synchronization power point. The linear ACPR value of the Class C main power signal, which has an extended gain linear dynamic range, is increased to 40-45 dBC or higher, or an inverse phase similar cancellation is achieved between a pre-distortion signal with inverse phase similar cancellation generated by a branch-like input cancellation circuit and a distortion signal that is larger than the input cancellation synchronization power point of the Class C main power signal, which has an extended gain linear dynamic range, of the main power signal of the branch-like input merging and main signal merging main circuit, and the gain linear dynamic range of the main power signal This extends the gain linear dynamic range of the Class C output main power signal, further extends it to smaller output main power signals, and improves the EVM value and gain fluctuations within the gain linear dynamic range of the signal already extended to smaller output main power signals, thereby extending the gain linear dynamic range of the main power signal of the merging main circuit of branch-like input merging and input cancellation, or further improves the linear ACPR value of the extended Class C main power signal to 40-45 dBC or higher, and also improves the overall mechanical efficiency of the power amplification circuit of similar merging and cancellation.

The output cancellation characteristics at the output terminal of the merging main circuit for branch-like input merging cancellation and branch-like output cancellation are as follows: When the linear ACPR value of a Class C main power signal, in which the gain linear dynamic range of the main power signal is extended at the output terminal of a merged main circuit of branch-like input merging and input cancellation reaches 40 to 45 dBC or higher, and the time delays at the output cancellation synchronization power points in the merged main circuit of branch-like input merging cancellation and branch-like output cancellation are equal or nearly equal, the amplitudes are equal or nearly equal, and the phases are opposite or nearly opposite, then a distortion signal having output inverse phase similar cancellation characteristics generated by a branch-like output cancellation circuit is considered to be a branch-like input merging and input cancellation. The distortion signal, which has an output phase inverse synchronous cancel at the output terminal of the branch-like input merged main circuit, is similar to the distortion signal of a Class C main power signal whose gain linear dynamic range is extended, and is similar to the output phase inverse synchronous cancel at the output terminal of the branch-like output cancel circuit, and the output phase inverse synchronous cancel at the output terminal of the branch-like input merged main circuit whose gain linear dynamic range is extended, and the output phase Distortion signals greater than the synchronous power point are canceled out, and the main power signal output from the merged main circuit of the branch-like input merge and branch-like output merge is further expanded, improving the linear ACPR value of the Class C main power signal to 50-55 dBC or higher, or the distortion signal having output inverse-phase synchronous cancelout generated by the branch-like output cancelout circuit and the output cancelout of the Class C main power signal whose gain linear dynamic range of the main power signal output from the merged main circuit of the main-like input merge and input cancelout is expanded Cancellation with distortion signals larger than the synchronous power point is achieved, and the gain linear dynamic range of the main power signal of the merged main circuit of the branch-like input merge and input cancelling is expanded by the reverse compensation characteristics of the Class C main power signal, which expands the gain linearity of the Class C output main power signal, which has an expanded gain linear dynamic range of the main power signal, and further expands to have a smaller output main power range, and further improves the EVM value and gain fluctuation within the expanded gain linear dynamic range.The main power signal output from the merging main circuit of the branch-like input merging cancellation and branch-output cancellation further improves the linear ACPR value of the extended Class C main power signal to 50-55 dBC or higher, and also improves the overall efficiency of the machine.
