Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is a national phase application filed under Article 371 of PCT / FR2019 / 050137 filed on January 22, 2019, which is hereby incorporated by reference in its entirety. Technical Field

[0003] Embodiments and examples of the present invention relate to electronic devices and methods, and more particularly, to phase detection electronic devices and methods. Background Art

[0004] Generally speaking, the goal of phase detection electronics (or in other words a phase detector) is to generate an output signal that is proportional to the phase difference between two input signals. Summary of the invention

[0005] Conventional phase detection electronics typically include either analog components, such as analog multipliers, or digital circuits, such as logic gates or flip-flops.

[0006] However, such electronic devices are not suitable for electromagnetic applications in the radio frequency (RF) field, especially electromagnetic applications in the millimeter wave band field.

[0007] There is therefore a need to provide a low complexity technical solution which will allow the detection of the phase of analogue signals in very high frequency electromagnetic applications without requiring extensive modifications to the electronic circuits used in such applications.

[0008] According to one aspect, a method of detecting the phase of an analog signal via a hybrid coupler operating in a power combiner mode is presented.

[0009] The hybrid coupler includes a first input that receives an analog signal, a second input that receives a reference signal having a reference phase and a frequency that is the same as that of the analog signal, and two outputs.

[0010] The hybrid coupler generates a first output signal and a second output signal at the two outputs, respectively.

[0011] The method includes measuring a peak value of an analog signal, a reference signal, and at least one of a first output signal and a second output signal, calculating a phase shift between a phase of the analog signal and a reference phase from the measured peak value, and determining a phase of the analog signal from the calculated phase shift and the reference phase.

[0012] This approach based on the use of hybrid couplers is advantageously inherently suitable for very high frequency electromagnetic applications.

[0013] Furthermore, this approach advantageously enables a low-complexity, non-intrusive solution for transmission paths comprising hybrid couplers.

[0014] By virtue of the intrinsic characteristics of the hybrid coupler, when the hybrid coupler operating in the power combiner mode receives an analog signal and a reference signal having the same frequency at its input end, respectively, a first signal and a second signal are obtained at the output end of the hybrid coupler, and the first signal and the second signal depend on the amplitudes of the analog signal and the reference signal, and the phase shift between the analog signal and the reference signal.

[0015] In other words, the peak value of the first output signal or the second output signal depends on the peak value of the analog signal and the peak value of the reference signal, and depends on the phase shift between the analog signal and the reference signal.

[0016] Therefore, once the peak values ​​of the first output signal or the second output signal, the analog signal and the reference signal are measured, the phase shift between the analog signal and the reference signal can be calculated from the measured peak values.

[0017] Since the reference signal has a known or preset reference phase, the phase of the analog signal can be determined from the calculated phase shift and the reference phase.

[0018] According to one embodiment, the hybrid coupler has a coupling factor whose value is selected between 0.8 and 1.0 and a calculated phase shift between -75° and 75°.

[0019] It should be noted that this embodiment takes into account the imperfections of the hybrid coupler and allows obtaining a reliable calculated phase shift.Such a range of calculated phase shifts advantageously makes it possible to obtain a satisfactory correspondence with the actually measured phase shift.

[0020] By way of non-limiting example, the hybrid coupler may be a 90° hybrid coupler.

[0021] In other words, the hybrid coupler can, for example, be a conventional orthogonal hybrid coupler, generally comprising: a first input terminal; a so-called isolated second input terminal coupled to an impedance (e.g., 50 ohms) when the coupler operates in a power divider mode; or a so-called coupled second input terminal when the coupler operates in a power combiner mode; or a so-called direct second input terminal when the coupler operates in a phase shifter mode; a so-called transmission first output terminal; and a so-called coupled second output terminal when the coupler operates in a power divider mode and in a phase shifter mode; or a so-called isolated second output terminal coupled to an impedance (e.g., 50 ohms) when the coupler operates in a power combiner mode.

[0022] According to another aspect, a method for adjusting the phase of an analog signal via a hybrid coupler operating in power combiner mode is proposed. The adjustment method comprises a method for detecting the phase of the analog signal as defined above so as to obtain a determined phase of the analog signal, a comparison between a setpoint phase and the determined phase of the analog signal, and if the setpoint phase differs from the determined phase of the analog signal, adjusting the phase of the analog signal until an equality within a tolerance is reached between the setpoint phase and the phase of the analog signal.

[0023] Advantageously, such a method allows the phase of the analog signal to be adjusted according to a setpoint phase after the phase of the analog signal has been determined, which is very useful, in particular during a calibration phase.

[0024] It should be noted that a person skilled in the art will be able to select a suitable tolerance depending on, for example, the envisaged application. By way of non-limiting illustration, the tolerance may, for example, be about 5%.

[0025] According to another aspect, an electronic device for detecting a phase of an analog signal is provided. The device comprises a hybrid coupler configured to operate in a power combiner mode.

[0026] The hybrid coupler comprises a first input intended to receive an analog signal, a second input intended to receive a reference signal having a reference phase and a frequency identical to that of the analog signal, and two outputs.

[0027] The hybrid coupler is configured to generate a first output signal and a second output signal at the two output ends, respectively.

[0029] According to one embodiment, the hybrid coupler has a coupling factor whose value is selected between 0.8 and 1.0 and the calculated phase shift is between -75° and 75°.

[0030] According to another embodiment, the hybrid coupler is a 90° hybrid coupler.

[0031] According to another aspect, a device for adjusting a phase of an analog signal via a hybrid coupler configured to operate in a power combiner mode is presented.

[0032] The adjustment device comprises a device as defined above for detecting the phase of an analog signal so as to obtain a determined phase of the analog signal, an adjustment circuit being coupled to the hybrid coupler and the adjustment circuit being configured to deliver the analog signal to the first input terminal and to deliver a set point signal having a set phase to the processing circuit.

[0033] The processing circuit of the detection device is further configured to compare the set point phase with the determined phase of the analog signal, and if the set point phase is different from the determined phase of the analog signal, adjust the phase of the analog signal through the adjustment circuit until an equality within tolerance is reached between the set point phase and the determined phase of the analog signal.

[0034] According to one embodiment, the adjustment circuit includes a transmission module configured to transmit an analog signal and adjust a determined phase of the analog signal according to a set point phase under control by the processing circuit.

[0035] According to another embodiment, the adjustment circuit includes: a transmission module, configured to transmit a set point signal and an analog signal; and a phase shifter, coupled between the transmission module and the first input terminal, and the phase shifter is configured to adjust a determined phase of the analog signal according to the set point phase under the control of the processing circuit.

The structure comprises: a regulating electronics such as defined above; an output device comprising a complementary hybrid coupler configured to operate in a power combiner mode; and a coupling stage coupled between the regulating electronics and the output electronics.

[0046] Figure 1 Reference numeral 1 in the drawing designates a communication device, for example here a communication device of the Wi-Fi router type according to the IEEE 802.11 group of standards.

[0047] By way of non-limiting example, the communication device 1 adopts beamforming technology to achieve directional transmission of signals.

[0048] The device 1 includes: a transmitting module, for example, a transceiver 2 here, which is configured to generate N analog signals SA1, SA2, SA3, SA4 (N is an integer equal to or greater than 2, for example, N is equal to 4 here); and N antennas ANT1, ANT2, ANT3, ANT4, which are respectively coupled to the transceiver 2 via four transmission paths CT1, CT2, CT3, CT4.

[0049] Each analog signal SA1 , SA2 , SA3 , SA4 is generated from a reference signal SREF having a reference frequency FREF and each analog signal SA1 , SA2 , SA3 , SA4 is intended to have a preset phase shift relative to the reference signal SREF.

[0050] The frequency of the analog signal is the same as the frequency of the reference signal.

[0051] In general, the transceiver 2 is configured to control the phase and amplitude of each analog signal SA1 , SA2 , SA3 , SA4 dedicated to a corresponding transmission path CT1 , CT2 , CT3 , CT4 .

[0052] After the signal processing operation performed by each transmission path CT1 , CT2 , CT3 , CT4 , each antenna ANT1 , ANT2 , ANT3 , ANT4 is configured to transmit an output signal SS1 , SS2 , SS3 , SS4 having a corresponding preset phase shift.

[0053] As a result, a pattern of destructive interference may be formed in the wavefront.On reception, the information originating from the different antennas ANT1, ANT2, ANT3, ANT4 is combined in such a way as to display the expected signal.

[0054] It should be noted that the performance of the directional transmission of these analog signals SA1 , SA2 , SA3 , SA4 is highly dependent on the phase shift accuracy of these analog signals SA1 , SA2 , SA3 , SA4 .

[0055] It is therefore advantageous to provide in each transmission path CT1 , CT2 , CT3 , CT4 a detection and optionally an adjustment of the phase of the analog signal SA1 , SA2 , SA3 , SA4 in order to ensure satisfactory performance of the directional transmission.

[0056] Now based on the reference Figure 2 An exemplary embodiment of one of the transmission paths CT1 , CT2 , CT3 , CT4 of the communication device 1 , here for example the first transmission path CT1 , is described in more detail.

[0057] The first transmission path CT1 is coupled between the transceiver 2 and the first antenna ANT1 and comprises an output electronic device DES1 coupled to the first antenna ANT1 and a coupling stage EC1 coupled between the input electronic device DEE1 and the output electronic device DES1 .

[0058] The input electronics DEE1 , the output electronics DES1 and the coupling stage EC1 together form a balanced power amplifier.

[0059] The input electronic device DEE1 comprises a first hybrid coupler CH1, for example here a 90° orthogonal hybrid coupler, comprising: a first input terminal BE1, coupled to the transceiver 2 and intended for receiving a first analog signal SA1 terminal; a so-called isolated coupled second input terminal BE2, which is coupled to an impedance (for example 50 ohms) when the coupler operates in a power divider mode; or a so-called coupled second input terminal BE2 when the coupler operates in a power combiner mode; a first output terminal BS1; and a second output terminal BS2.

[0060] The output electronic device DES1 comprises: a second hybrid coupler CH2, here also a 90° orthogonal hybrid coupler, which operates in a power combiner mode and comprises: a third input terminal BE3; a fourth input terminal BE4; a so-called isolated, coupled third output terminal BS3, which is coupled to an impedance (e.g. 50 ohms); and a fourth output terminal BS4, which is coupled to the first antenna ANT1 and is configured to pass a first output signal SS1 to the first antenna ANT1.

[0061] The coupling stage EC1 comprises a first coupling module MC1 connected in parallel between the first output terminal BS1 and the third input terminal BE3 , and a second coupling module MC2 connected in parallel between the second output terminal BS2 and the fourth input terminal BE4 .

[0062] The first coupling module MC1 here comprises, for example, a first driver stage and a first power controller connected in series between the first output terminal BS1 and the third input terminal BE3 .

[0063] The second coupling module MC2 comprises a second driver stage and a second power controller connected in series between the second output terminal BS2 and the fourth input terminal BE4.

[0064] By way of non-limiting illustration, when the first transmission path CT1 is used, the first hybrid coupler CH1 operates in a power divider mode and the second hybrid coupler CH2 operates in a power combiner mode.

[0065] In order to ensure that the phase of the first analog signal SA1 received at the first input terminal BE1 corresponds to the first set point phase PC1 , the first transmission path CT1 is further configured to detect and adjust the phase of the first analog signal SA1 .

[0066] An example of a method for detecting and adjusting the phase of the first analog signal SA1 is now also referred to Figure 3 describe.

[0067] To do this, the first transmission path CT1 is operated in a detection mode or a regulation mode and the first hybrid coupler CH1 is operated in a power combiner mode.

[0068] The second input terminal BE2 is intended in this detection or adjustment mode to receive a reference signal SREF having the same frequency as the first analog signal SA1 and a known reference phase. The second input terminal BE2 is intended here, for example, to receive the reference signal SREF.

[0069] The first transmission path CT1 includes a first measurement circuit MM1, which includes: a first peak detector DC1, coupled to the first input terminal BE1 and configured to measure the peak value A1 of the first analog signal SA1; a second peak detector DC2, coupled to the second input terminal BE2 and configured to measure the peak value A2 of the reference signal SREF; a third peak detector DC3, coupled to the first output terminal BS1 and configured to measure the peak value A3 of the first output signal SS1 passed by the first hybrid coupler CH1 to the first output terminal BS1; and a fourth peak detector DC4, coupled to the second output terminal BS2 and configured to measure the peak value A4 of the second output signal SS2 passed by the second hybrid coupler CH2 to the second output terminal BS2.

[0070] The structures of the first peak detector, the second peak detector, the third peak detector and the fourth peak detector DC1, DC2, DC3, DC4 are common knowledge to those skilled in the art, and each peak detector DC1, DC2, DC3, DC4 may, for example, include an amplifier, a diode and a capacitor (not shown) installed in a follower configuration.

[0071] In this first step STP1 , the first measurement circuit MM1 is configured to measure the peak values ​​A1 , A2 , A3 , A4 .

[0072] The first transmission path CT1 further comprises a first processing circuit MT1 ( Figure 3 STP2 in ).

[0073] Specifically, the first analog signal SA1 can be described by the equation in the time domain:

[0074] SA1(t)=A1*cos(ω*t+Φ1),

[0075] Where ω is the angular frequency of the first analog signal:

[0076] ω=2π*FREF

[0077] And Φ1 is the phase of the first analog signal SA1.

[0078] The reference signal SREF can be described by another equation in the time domain:

[0079] SREF(t)=A2*cos(ω*t+Φ2),

[0080] Where Φ2 is the reference phase.

[0081] In the same manner, the first output signal SS1 and the second output signal SS2 can be written as follows.

[0082]

[0083]

[0084] By isolating Φ1-Φ2, the following results can be obtained:

[0085] or

[0086]

[0087] Therefore, the phase shift between the first analog signal SA1 and the reference signal SREF is calculated from the peak values ​​A1 , A2 , A3 , A4 of the first analog signal SA1 , the reference signal SREF and the first output signal SS1 or the second output signal SS2 .

[0088] Since the reference phase Φ2 is known, the phase Φ1 of the first analog signal SA1 can be calculated by the first processing circuit MT1 .

[0089] It should be noted that the above equations are based on an ideal hybrid coupler, in other words a coupler having a coupling coefficient equal to 1, as known to those skilled in the art.

[0090] In practical cases, it is preferred to use a hybrid coupler with a coupling coefficient, the value of which is chosen between 0.8 and 1.0. In these cases, the calculated phase shift values ​​between -75° and 75° do correspond to the directly measured phase shift values.

[0091] The transceiver 2 is further coupled to the first processing circuit MT1 and is configured to deliver a first setpoint signal SC1 having a first setpoint phase PC1 to the first processing circuit MT1 .

[0092] The first processing circuit MT1 is further configured to compare the first set point phase PC1 with the first analog signal SA1 ( Figure 3 The determined phase Φ1 of STP3) in .

[0093] If the first set point phase PC1 and the determined phase Φ1 of the first analog signal SA1 are different, the transceiver 2 is configured to adjust the phase Φ1 of the first analog signal SA1 under the control of the first processing circuit MT1 so as to adjust the phase Φ1 to the first set point phase PC1 ( Figure 3 STP4 in the align to within tolerance.

[0094] Thus, a device for detecting and adjusting the phase of an analog signal SA1 via a hybrid coupler CH1 is obtained, which device forms a low-complexity solution, non-intrusive to electromagnetic applications already involved, in particular one or more hybrid couplers.

[0095] It should be noted that in Figure 2 In the example shown, the transceiver 2 forms a regulating circuit MR configured to adjust the phase Φ1 of the first analog signal SA1 under control by the first processing circuit MT1 .

[0096] As a variant, the phase Φ1 and the first setpoint phase PC1 can be adjusted outside the transceiver 2 .

[0097] Now we will refer to Figure 4 and reference Figure 5 Another embodiment of the first transmission path CT1 of the communication device 1 and a corresponding another exemplary implementation for detecting and adjusting the phase Φ1 of the first analog signal SA1 are shown.

[0098] Figure 4 The first transmission path CT1 in Figure 2 and more particularly comprises a phase shifter DEPH coupled between the transceiver 2 and the first input terminal BE1 and configured to adjust the phase Φ1 of the first analog signal SA1 delivered by the transceiver 2 under control by the first processing circuit MT1.

[0099] In this case, the regulation circuit MR comprises a phase shifter DEPH and a transceiver 2 .

[0100] By Figure 4 The method for detecting the phase Φ1 of the first analog signal SA1 performed on the first transmission path CT1 in Figure 3 The method illustrated in FIG. 1 is the same as that illustrated in FIG. 1 and comprises: a first step STP1, wherein the first measurement circuit MM1 is configured to measure the peak values ​​A1, A2, A3, A4 of the first analog signal SA1, the first analog signal SA1, the reference signal SREF and the first output signal SS1 and / or the second output signal SS2; and a second step STP2, wherein the first processing circuit MT1 is configured to calculate the phase shift (Φ1-Φ2) between the phase Φ1 and the reference phase Φ2 using one of the following two equations:

[0101] or

[0102]

[0103] And the phase Φ1 is determined according to the calculated phase shift Φ1-Φ2 and the reference phase Φ2.

[0104] Depend on Figure 4 The method for adjusting the phase Φ1 of the first analog signal SA1 performed on the first transmission path CT1 further includes: a third step STP3, wherein the first processing circuit MT1 is configured to receive the first set point signal SC1 having a first set point phase PC1, and compare the first set point phase PC1 with the determined phase Φ1; and a fourth step STP4DEPH, in which if the first set point phase PC1 is different from the determined phase Φ1, the phase shifter DEPH is configured to adjust the determined phase Φ1 of the first analog signal SA1 according to the first set point phase PC1 under the control of the first processing circuit MT1 until the first set point phase PC1 and the determined phase Φ1 of the first analog signal SA1 are equal within the tolerance.

[0105] By way of non-limiting indication, Figure 6 An exemplary embodiment of a phase shifter DEPH is illustrated.

[0106] The phase shifter DEPH includes: a first phase shift channel VD1, a second phase shift channel VD2, an input switch CIN and an output switch COUT, the input switch CIN is coupled to the transceiver 2 and is configured to switch between the first phase shift channel VD1 and the second phase shift channel VD2, and the output switch COUT is coupled to the first input terminal BE1 and is configured to switch between the first phase shift channel VD1 and the second phase shift channel VD2.

[0107] The first phase shift channel VD1 includes: a first input node NE1, a first output node NS1, a first inductor L1, a first adjustable capacitor C1 and a second adjustable capacitor C2, the first inductor L1 is coupled between the first input node NE1 and the first output node NS1, the first adjustable capacitor C1 is coupled between the first input node NE1 and the ground GND, and the second adjustable capacitor C2 is coupled between the first output node NS1 and the ground GND.

[0108] When the phase shifter DEPH is configured to delay the determined phase Φ1 of the first signal SA1 under the control of the first processing circuit MT1, the input switch CIN and the output switch COUT are configured to select the first phase shift channel VD1 and adjust the determined phase Φ1 of the first analog signal SA1 according to the first set point phase PC1 until the first set point phase PC1 reaches equality with the determined phase Φ1 of the first analog signal SA1 within a tolerance.
