Description

Technical Field

[0001] This utility model relates to the field of microwave antennas, and in particular to a Ku-band active phased array antenna transceiver assembly and an active phased array antenna system. Background Technology

[0002] In the field of microwave antennas, microstrip planar antennas or waveguide slot array antennas are commonly used. In these antennas, the microwave signal only needs to be amplified through transceiver components, and the transmit pulse frequency and duty cycle are controlled by manipulating the transmit and receive time slots; phase and amplitude control are not required. To ensure the dual-polarization operation of microstrip planar antennas or waveguide slot array antennas, their receiving and transmitting channels need to be designed as dual-path channels to ensure that both polarization signals can be received and transmitted normally. However, this results in larger size, higher power consumption, and higher cost for microstrip planar antennas or waveguide slot array antennas.

[0003] Ku-band active phased array antenna transceiver components are used in active phased array antennas and require phase and amplitude control. Polarization switches are used to select the operating state of different polarizations of the active phased array antenna, and online phase and amplitude calibration is also provided. Existing active phased array antennas typically use multi-stage cascaded circuits for their receive and transmit channels, which increases the difficulty of debugging and testing parameters such as gain flatness and gain consistency between channels.

This addresses the problem that existing active phased array antennas typically employ multi-stage cascading circuits for their receiving and transmitting channels, which increases the difficulty of debugging and testing parameters such as gain flatness and gain consistency between channels.

[0042] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] In one embodiment, such as Figure 1 As shown, this utility model provides a KU-band active phased array antenna transceiver assembly 100, including: several antenna polarization interfaces 10, several transceiver channel assemblies 20, a phase-shifting attenuation multi-function chip 30, a combiner 40, and an RF connector 50. One antenna polarization interface 10 is electrically connected to one transceiver channel assembly 20, and one transceiver channel assembly 20 forms a dual-polarization channel with one antenna polarization interface 10. Each transceiver channel assembly 20 is electrically connected to the phase-shifting attenuation multi-function chip 30, the phase-shifting attenuation multi-function chip 30 is electrically connected to the combiner 40, and the combiner 40 is electrically connected to the RF connector 50.

[0044] In this embodiment, a Ku-band active phased array antenna transceiver component is provided, including several antenna polarization interfaces, several transceiver channel components, a phase-shifting attenuation multifunction chip, a combiner, and an RF connector. One antenna polarization interface is electrically connected to one transceiver channel component, and one transceiver channel component forms a dual-polarization channel with one antenna polarization interface. Each transceiver channel component is electrically connected to the phase-shifting attenuation multifunction chip, the phase-shifting attenuation multifunction chip is electrically connected to the combiner, and the combiner is electrically connected to the RF connector. Thus, by electrically connecting one antenna polarization interface to one transceiver channel component to form a dual-polarization channel, the receiving and transmitting channels do not need to be implemented using multi-stage cascaded circuits, enabling time-division multiplexing of dual-polarization signal transmission and reception, improving the operational capability of the active phased array antenna. Furthermore, by electrically connecting each transceiver channel component to the phase-shifting attenuation multifunction chip, and the phase-shifting attenuation multifunction chip to the combiner, the difficulty of debugging and testing parameters such as gain flatness and gain consistency between channels can be reduced. This can solve the problem that existing active phased array antennas generally use multi-stage circuit cascades to implement the receiving and transmitting channels, which increases the difficulty of debugging and testing indicators such as gain flatness and gain consistency between channels.

[0045] In one embodiment, such as Figure 1 As shown, the KU-band active phased array antenna transceiver assembly 100 includes several transceiver channel assemblies 20. Each transceiver channel assembly 20 includes: a transmit channel assembly 21, a receive channel assembly 22, a ring isolator 25, and a polarization switch chip 23; wherein:

[0046] The transmit channel assembly 21 is electrically connected to the phase-shift attenuation multifunctional chip 30 and the ring isolator 25 respectively, and is used to output the microwave transmit signal from the phase-shift attenuation multifunctional chip 30 to the ring isolator 25 in the transmit state.

[0047] The receiving channel component 22 is electrically connected to the phase-shifting attenuation multifunctional chip 30 and the ring isolator 25 respectively, and is used to output the microwave received signal from the ring isolator 25 to the phase-shifting attenuation multifunctional chip 30 in the receiving state.

[0048] The ring isolator 25 is electrically connected to the polarization switch chip 23 and is used to separate the microwave transmission signal from the transmission channel assembly 21 and output it to the polarization switch chip 23; and to separate the microwave reception signal from the polarization switch chip 23 and output it to the reception channel assembly 22.

[0049] The polarization switch chip 23 is electrically connected to the antenna polarization interface 10 and is used to select the operating state of the active phased array antenna with different polarizations. Specifically, it is used to: transmit the microwave transmission signal from the ring isolator 25 to the antenna polarization interface 10 where the selected dual polarization channel is located after signal polarization processing, and transmit the microwave reception signal from the antenna polarization interface 10 to the ring isolator 25 after signal polarization processing.

[0050] Furthermore, each of the transmit channel components 21 includes a transmit power amplifier component, which is electrically connected to the phase-shift attenuation multifunction chip 30 and the ring isolator 25, respectively. In the transmit state, the transmit power amplifier component amplifies the microwave transmit signal output from the phase-shift attenuation multifunction chip 30 and outputs it to the ring isolator 25. The transmit power amplifier component includes a medium-power amplifier 211 and a high-power amplifier 212; wherein:

[0051] The medium power amplifier 211 is electrically connected to the phase-shift attenuation multifunctional chip 30 and the high power amplifier 212 respectively. In the transmission state, it performs the first stage power amplification on the microwave transmission signal output from the phase-shift attenuation multifunctional chip 30 and outputs the microwave transmission signal after the first stage power amplification to the high power amplifier 212.

[0052] The high-power amplifier 212 is electrically connected to the medium-power amplifier 211 and the ring isolator 25 respectively. In the transmission state, it performs a second-stage power amplification on the microwave transmission signal output by the medium-power amplifier 211 after the first-stage power amplification, and outputs the microwave transmission signal after the second-stage power amplification to the ring isolator 25.

[0053] Furthermore, each receiving channel component 22 includes: a limiter 221 and a low-noise amplifier 222, wherein:

[0054] Limiter 221 is electrically connected to ring isolator 25 and low noise amplifier 222 respectively, and is used to limit the amplitude of microwave received signal output from ring isolator 25 in receiving mode and output it to low noise amplifier 222.

[0055] The low-noise amplifier 222 is electrically connected to the limiter 221 and the phase-shift attenuation multi-function chip 30, respectively, and is used to amplify the microwave received signal output from the limiter 221 and output it to the phase-shift attenuation multi-function chip 30.

[0056] In this embodiment, the transceiver channel component includes one transmit channel component, one receive channel component, a ring isolator, and a polarization switch chip, enabling the Ku-band active phased array antenna transceiver component to have dual-channel communication. The polarization switch chip enables the selection of the operating state of different polarization antennas of the Ku-band active phased array antenna, which can realize time-division transmission and reception of dual-polarization signals and improve the working capability of the active phased array antenna.

[0057] In one embodiment, such as Figure 1 As shown, the phase-shifting attenuation multi-function chip 30 is electrically connected to several transceiver channel components 20 and a combiner 40, respectively, to complete the amplitude and phase control of the several transceiver channel components 20.

[0058] Specifically, in the transmission state, the phase-shifting attenuation multi-function chip 30 processes the amplitude and phase of several equal-amplitude and in-phase channel signals obtained from the combiner 40, and then transmits several microwave transmission signals to the corresponding transmission channel components 21 in several transceiver channel components 20.

[0059] In the receiving state, the phase-shifting attenuation multi-function chip 30 processes the amplitude and phase of the microwave received signal from the receiving channel component 22 in the several transceiver channel components 20 and then transmits it to the combiner 40.

[0060] In this embodiment, each transceiver channel component is electrically connected to a phase-shifting attenuation multifunctional chip. The phase-shifting attenuation multifunctional chip completes the amplitude and phase control of several transceiver channel components, which can reduce the difficulty of debugging and testing indicators such as gain flatness and gain consistency between channels.

[0061] In one embodiment, such as Figure 1 As shown, the combiner 40 is electrically connected to the phase-shifting attenuation multi-function chip 30 and the RF connector 50, respectively.

[0062] Specifically, in the transmitting state, the combiner 40 converts the microwave transmission signal from the RF connector 50 into several equal-amplitude, in-phase channel signals, which are then transmitted to the phase-shifting attenuation multi-functional chip 30.

[0063] In the receiving state, the combiner 40 combines several microwave received signals from the phase-shifting attenuation multi-function chip 30 to form a combined signal, which is then transmitted to the RF connector 50.

[0064] In one embodiment, such as Figure 1 As shown, the RF connector 50 is electrically connected to the combiner 40 for receiving input microwave signals and transmitting them to the combiner 40 in the transmitting state; and for receiving combined signals transmitted from the combiner 40 in the receiving state.

[0065] The polarized antenna interface 1 is electrically connected to the transceiver channel assembly 20. Specifically, the polarized antenna interface 1 is electrically connected to the polarization switch chip 23 in the transceiver channel assembly 20.

[0066] In the transmit state, the polarized antenna interface 1 transmits the signal from the transmit channel in the transceiver channel assembly 20, after signal polarization processing by the polarization switch chip 23, to the external device connected to it.

[0067] In receiving mode, the polarized antenna interface 1 receives microwave signals from external input and transmits them to the polarization switch chip 23.

[0068] In one embodiment, such as Figure 1 As shown, the transceiver channel assembly 20 also includes a coupler 24, which is disposed between the polarization switch chip 23 and the ring isolator 25, for coupling a portion of the energy in the transceiver channel to the calibration network 60. Figure 2 This is a simulation model of coupler 24. Figure 3 These are the simulation results of the simulation model of coupler 24.

[0069] The KU-band active phased array antenna transceiver assembly 100 also includes a calibration network 60, which is electrically connected to couplers 24 integrated in each transceiver channel for online phase and amplitude calibration based on a portion of the energy in the transceiver channel.

[0070] Specifically, in the transmission state, when the microwave transmission signal passes through the coupler 24, the coupler 24 couples part of the energy into the calibration network 60, so that the calibration network 60 can realize online phase and amplitude calibration of the microwave transmission signal.

[0071] In the receiving state, when the calibration signal transmitted by the calibration network 60 passes through the coupler 24, the coupler 24 couples part of the energy into the receiving channel to realize online phase and amplitude calibration of the microwave received signal.

[0072] In this embodiment, by setting a coupler between the polarization switch chip and the ring isolator, it is equivalent to setting a coupler in each transceiver channel. The calibration network is electrically connected to the couplers integrated in each transceiver channel. The calibration network adds a calibration signal input to both the received microwave signal and the transmitted microwave signal, which can monitor the signal quantity of the microwave transmitted signal and the microwave received signal at all times. This can help the active phased array antenna system to realize the self-test of the active phased array antenna's working status and the online self-calibration of phase and amplitude, thereby improving the reliability of the active phased array antenna system.

[0073] In one embodiment, such as Figure 1As shown, the KU-band active phased array antenna transceiver assembly 100 also includes a low-frequency control circuit 70. The low-frequency control circuit 70 is electrically connected to the medium-power amplifier 211, high-power amplifier 212, low-noise amplifier 222, limiter 221, and phase-shift attenuation multi-function chip 30, respectively. It provides the rated voltage and drive current required for the operation of the medium-power amplifier 211, high-power amplifier 212, low-noise amplifier 222, limiter 221, and phase-shift attenuation multi-function chip 30, and controls their operating states by driving the N-channel MOSFET in the low-frequency control circuit 70 through a control signal. Figure 4 This is the circuit schematic of the N-channel MOSFET in the low-frequency control circuit 70.

[0074] The low-frequency control circuit 70 drives the high-voltage PIN driver in the low-frequency control circuit 70 to drive the polarization switch chip 23 through the control signal, thereby controlling the working state of the polarization switch chip 23 in the transceiver channel. Figure 5 This is the circuit schematic of the high-voltage PIN driver in the low-frequency control circuit 70.

[0075] In one embodiment, such as Figure 6 As shown, the KU-band active phased array antenna transceiver assembly 100 also includes: a microwave substrate 80, a low-frequency control circuit 70, a medium-power amplifier 211, a high-power amplifier 212, a low-noise amplifier 222, a limiter 221, a phase-shifting attenuation multi-functional chip 30, a combiner 40, and a ring isolator 25 disposed on the microwave substrate 80.

[0076] In one embodiment, the KU-band active phased array antenna transceiver assembly 100 further includes: a housing, a microwave substrate 80 disposed inside the housing, a plurality of radio frequency connectors 50 disposed on a first side of the housing, and a plurality of antenna polarization interfaces 10 disposed on a second side of the housing.

[0077] The front and back sides of the package housing are different circuit layers, which include gold wire bonding, microstrip transmission and connector conversion structure. The gold wire bonding, microstrip transmission and connector conversion structure are laser-sealed to the front and back sides of the package housing.

[0078] For example, the wiring layer on the front side of the package housing includes microstrip transmission and connector conversion structures, which are laser-sealed to the front side of the package housing. The wiring layer on the back side of the package housing includes gold wire bonding, which is laser-sealed to the back side of the package housing.

[0079] For example, it can be like Figure 6The diagram shown illustrates the front assembly of the KU-band active phased array antenna transceiver assembly. The transceiver is laser-sealed into the front of the package housing, allowing it to be assembled as shown. Figure 7 The schematic diagram of the back assembly of the KU-band active phased array antenna transceiver shown is illustrated by laser sealing to the back of the package housing.

[0080] In this embodiment, by setting different circuit layers on the front and back of the package housing, placing the microwave substrate in the package housing, setting several RF connectors on the first side of the package housing, and setting several antenna polarization interfaces on the second side of the package housing, a hermetically sealed design is formed, making the Ku-band active phased array antenna transceiver component compact and realizing the functions that are traditionally achieved by integrating various independent microwave modules. It can also solve the problems of large size, high power consumption, and high cost of existing traditional microwave antennas.

[0081] This utility model provides a Ku-band active phased array antenna transceiver assembly 100, the working principle of which is as follows:

[0082] In the transmitting state, the microwave transmission signal is input from the RF connector 50, which converts the RF signal into a transmission signal for the microwave substrate 80. The microwave transmission signal is transmitted in the microwave substrate 80. When the microwave transmission signal passes through the combiner 40, the combiner 40 converts the microwave transmission signal into two microwave transmission signals with equal amplitude and phase. The two microwave transmission signals pass through the phase-shifting attenuation multi-function chip 30, where amplitude and phase processing are performed. After amplitude and phase processing, the microwave transmission signal is transmitted through the microwave substrate 80 and output to the medium-power amplifier 211 in the transmission channel assembly 21 for the first stage of power amplification. After the second stage of power amplification by the high-power amplifier 212, it is separated by the ring isolator 25 and output to the polarization switch chip 23. The polarization switch chip 23 performs signal polarization processing on the microwave transmission signal and outputs it from the dual-polarization channel selected by the polarization switch chip 23 to the corresponding antenna polarization interface 10, and then transmits it to the external device connected to it through the antenna polarization interface 10. A coupler 24 is located between the polarization switch chip 23 and the ring isolator 25. When the microwave transmission signal passes through the coupler 24, part of the energy is coupled into the calibration network 60 so that the calibration network 60 can perform online phase and amplitude calibration of the microwave transmission signal.

[0083] In the receiving state, the microwave receiving signal is input from the antenna polarization interface 10, which converts the microwave receiving signal into a transmission signal for the microwave substrate 80. The microwave receiving signal is then transmitted in the microwave substrate 80 to the polarization switch chip 23, where it undergoes corresponding polarization signal processing. It is then transmitted through the microwave substrate 80 to the ring isolator 25. The ring isolator 25 separates the microwave receiving signal from the polarization switch chip 23 and outputs it to the limiter 221 of the receiving channel assembly 22. The limiter 221 limits the amplitude of the microwave receiving signal to protect the low-noise amplifier 222 at the back end. The microwave receiving signal is amplified by the low-noise amplifier 222 and input to the phase-shift attenuation multifunction chip 30. The phase-shift attenuation multifunction chip 30 processes the amplitude and phase of the microwave receiving signal before transmitting it through the microwave substrate 80 to the combiner 40. The combiner 40 combines several microwave receiving signals from the phase-shift attenuation multifunction chip 30 to form a combined signal, which is then output to the corresponding RF connector 50. A coupler 24 is located between the polarization switch chip 23 and the ring isolator 25. When the calibration signal emitted by the calibration network 60 passes through the coupler 24, part of the energy is coupled into the receiving channel to achieve online phase and amplitude calibration of the microwave receiving signal.

[0084] This utility model provides a Ku-band active phased array antenna transceiver assembly 100 in which a phase-shifting attenuation multi-functional chip 30 can control two transceiver channel assemblies 20 (such as...). Figure 1 (As shown). In this scenario, during transmission, the combiner 40 converts the microwave transmission signal from the RF connector 50 into two equal-amplitude, in-phase channel signals, which are then transmitted to the phase-shifting attenuation multifunction chip 30. The phase-shifting attenuation multifunction chip 30 processes the amplitude and phase of the two equal-amplitude, in-phase channel signals and transmits them to the transmission channel components 21 of the two transceiver channel components 20. During reception, the receiving channel components 22 of the two transceiver channel components 20 receive microwave reception signals from the antenna polarization interface 10. The two receiving channel components 22 input their respective received microwave reception signals to the phase-shifting attenuation multifunction chip 30. The phase-shifting attenuation multifunction chip 30 processes the amplitude and phase of the two microwave reception signals and transmits them to the combiner 40. The combiner 40 combines the two received microwave reception signals to form a combined signal, which is then output to the corresponding RF connector 50.

[0085] It is understood that in the Ku-band active phased array antenna transceiver assembly 100 provided by this utility model, one phase-shifting attenuation multi-functional chip 30 can also control the four-channel transceiver assembly 20 (e.g., Figure 6(As shown). In this scenario, during transmission, the combiner 40 converts the microwave transmission signal from the RF connector 50 into two equal-amplitude, in-phase channel signals, which are then transmitted to the phase-shifting attenuation multifunction chip 30. The phase-shifting attenuation multifunction chip 30 then processes the amplitude and phase of the two equal-amplitude, in-phase channel signals and, based on a preset allocation strategy, transmits the two signals to the transmission channel components 21 of two of the transceiver channel components 20, or simultaneously allocates one signal to the transmission channel components 21 of two of the transceiver channel components 20, and simultaneously allocates the other signal to the transmission channel components 21 of the remaining two transceiver channel components 20. In the receiving state, the receiving channel component 22 of the four-channel transceiver component 20 receives microwave received signals from the antenna polarization interface 10. The four receiving channel components 22 respectively input their received microwave received signals to the phase shift attenuation multi-function chip 30. The phase shift attenuation multi-function chip 30 processes the amplitude and phase of the two microwave received signals and then transmits them to the combiner 40. The combiner 40 combines the two received microwave received signals to form a combined signal, which is then output to the corresponding RF connector 50.

[0086] Similarly, it is understood that the Ku-band active phased array antenna transceiver assembly 100 provided by this utility model includes two or more phase-shifting and attenuation multi-functional chips 30, each of which can control two or four transceiver channels 20. For example, as Figure 6As shown, the KU-band active phased array antenna transceiver assembly 100 includes four phase-shift attenuation multifunction chips 30, each of which controls four transceiver channel assemblies 20. The KU-band active phased array antenna transceiver assembly 100 has a total of 16 transceiver channel assemblies 20, two combiners 40, and two RF connectors 50. Each combiner 40 is electrically connected to two phase-shift attenuation multifunction chips 30. In this scenario, during the transmission state, taking one of the combiners as an example, the combiner 40 converts the microwave transmission signal from the RF connector 50 into two equal-amplitude, in-phase channel signals, which are then transmitted to two phase-shifting attenuation multifunction chips 30 electrically connected to it. Each phase-shifting attenuation multifunction chip 30 receives one equal-amplitude, in-phase channel signal. After processing the amplitude and phase of the received equal-amplitude, in-phase channel signal, each phase-shifting attenuation multifunction chip 30 transmits the signal only to the transmission channel component 21 of one of the transceiver channel components 20 based on a preset allocation strategy, or transmits the signal simultaneously to the transmission channel components 21 of two, three, or four of the transceiver channel components 20. In the receiving state, the receiving channel component 22 of the four-channel transceiver component 20 receives microwave received signals from the antenna polarization interface 10. The four receiving channel components 22 respectively input their received microwave received signals to the phase shift attenuation multifunction chip 30. The phase shift attenuation multifunction chip 30 processes the amplitude and phase of the four microwave received signals and then transmits them to the combiner 40. The combiner 40 receives the eight microwave received signals transmitted from the two phase shift attenuation multifunction chips 30, completes signal combining, and forms a combined signal, which is then output to the corresponding RF connector 50.
