Problems solved by technology
[0006] In order to solve the mutual interference caused by the integration of the antennas used in the two satellite communication systems compatible with the S-band into one compatible antenna in the prior art, and because the two antennas have different polarization modes, the integrated compatible antenna needs to meet the circular polarization adjustable rotation Functional problems, the present invention uses a microwave switch to cooperate with a band-pass filter to form a double-branch switching design in a single channel, and proposes a new type of transceiver for the airborne phased array antenna compatible with two S-band satellite communication systems The component and the phased array antenna with the transceiver component, through the design of synthesizing two receiving / transmitting channels into one receiving / transmitting channel to feed the antenna unit, realizes adjustable polarization

Embodiment Construction
[0041] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.
[0042] Such as figure 1 As shown, in the prior art, the transmitting and receiving frequency bands of the L-pass and T-pass satellite communication systems are close to each other and cross each other, which will cause interference to the corresponding receiving channel (including: when the T-pass transmits, the signal leaked to the L-pass receiving frequency band ; When L-pass transmits, it leaks to the signal of T-pass receiving frequency band), these interference signals need to be effectively filtered to avoid mutual interference between the two systems.
[0043] Such as figure 2 As shown, a phased array antenna transceiver assembly (hereinafter referred to as the transceiver assembly) is disclosed in Embodiment 1, which mainly consists of a feed interface layer 1, a receiving channel 2, a receiving channel cold plate 3, a transmitting ch...

The invention discloses a highly integrated four-channel S-band transceiver module, comprising a receiving channel, a transmitting channel and an external interface, wherein the receiving channel comprises paired band branch I and Q receiving channels, and the transmitting channel comprises paired band branch I and Q transmitting channels. The two-port feeding of the transceiver module can effectively improve the circular polarization axis ratio of the antenna, and the transceiver channels are separated, which can improve the isolation of the transceiver, reduce the interference between channels and help to improve the communication capability of the system. Furthermore, the invention also discloses a phased array antenna with the high-integration four-channel S-frequency transceiver module, which can realize polarization adjustability by cooperating with a four-point feeding antenna unit, realizes polarization conversion and beam scanning of the phased array antenna through electroniccontrol phase shift and branch switching, effectively reduces the antenna port surface, and realizes miniaturization design.
