[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0034] Embodiment 1

[0035] A dual-band multi-channel TR module, as Figure 1 shown, is the principle block diagram of the present invention. 1A1 to 1A2 are Ku-band power amplifier circuits, 1B1 to 1B2 are Ku-band low-noise amplifier circuits, 1C1 to 1C2 are Ku-band amplitude-phase multifunctional circuits, 1D is a Wilkinson power divider circuit, 2A1 to 2A4 are Ka-band power amplifier circuits, 2B1 to 2B4 are Ka-band low-noise amplifier circuits, K1 to K4 are Ka-band switch circuits, and 2C1 is a Ka-band amplitude-phase multifunctional circuit.

[0036] As Figures 2 to 4 shown, 41 is the Ku-band common interface, 44 is the Ka-band common interface, 42 is the Ku-band receive input, with a quantity of 2, 43 is the Ku-band transmit output, with a quantity of 2, 45 is the Ka-band transmit output, with a quantity of 4, 46 is the Ka-band transmit output, with a quantity of 4, and 47 is the video signal port.

[0037] It can be seen from Figure 1 that the dual-band TR module integrates 2 Ku-band transceiver channels and 4 Ka-band transceiver channels. When the Ku-band receives, the received signal enters the product through the Ku antenna, passes through the low-noise amplifiers 1B1 to 1B2 and the amplitude-phase multifunctional circuits 1C1 to 1C2 respectively, and then is synthesized by the Wilkinson power divider 1D and output to the Ku power distribution network. When the Ka-band receives, the received signal enters the product through the Ka antenna, passes through the low-noise amplifiers 2B1 to 2B4 and the RF switches K1 to K4 respectively, and then is synthesized by the four-channel integrated amplitude-phase multifunctional circuit 2C1 and output to the Ka power distribution network.

[0038] When operating in the Ku - band transmission mode, the transmission signal enters the product through the Ku power - dividing network. It is divided into two RF signals by the Wilkinson power divider 1D and then transmitted to the amplitude - phase multi - function units 1C1 - 1C2 respectively. After being adjusted to the appropriate phase state, the RF signals are output to the Ku antenna for radiation through the power amplifiers 1A1 - 1A2. When operating in the Ka - band transmission mode, the transmission signal enters the product through the Ka power - dividing network. It is divided into four RF signals with different phase states by the four - channel integrated amplitude - phase multi - function unit 2C1 and then transmitted to the RF switches K1 - K4 respectively. Then, the RF signals are output to the Ka antenna for radiation through the power amplifiers 2A1 - 2A4.

[0039] The utility model independently designs the receiving and transmitting interfaces, removes the circulator or switch shared by receiving and transmitting in the conventional ports, optimizes the product indicators, and the receiving and transmitting link indicators are optimized by 1 dB.

[0040] The utility model can realize the integrated design of 2 Ku - band receiving and transmitting channels and 4 Ka - band receiving and transmitting channels. To reduce the circuit complexity and save space, different from the traditional design, within the size of the conventional Ku - band receiving and transmitting channels, 4 Ka - band receiving and transmitting channels are added in a back - to - back form through double - sided layout. And by reasonably allocating the DC control nodes, the Ku - band and Ka - band can work independently.

[0041] As Figure 5 shown, the utility model adopts the surface - buried resistor design. By optimizing the size of the buried resistor, the anti - burnout power of the buried resistor is improved. The isolation resistor on the Wilkinson power divider 1D and the port 47 protection resistor of the control signal are both realized in the form of surface - buried resistors, which improves the integration of the microwave multi - layer board and simplifies the subsequent assembly work.

[0042] The above - mentioned is only the preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution and the inventive concept of the utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the utility model.
