Description

Transceiver device for high frequency satellite communication

technical field

The utility model relates to a transceiver device applied to high-frequency satellite communication, and in particular to a transceiver device applied to high-frequency satellite communication with a receiving end terminal element.

Background technique

The receiving path of the high-frequency satellite communication system receives a satellite signal through a waveguide, and after being processed by an analog processing element, such as an analog chip, the satellite signal is then transferred to a digital processing element, such as a digital chip for follow-up signal processing.

In the known high-frequency satellite communication transceiver, the waveguide receives the received satellite signal from a waveguide input terminal, and conducts it to a receiving terminal through the waveguide, and then transmits it to an analog processing element. In terms of the transmission path, the waveguide receives signals to be transmitted from an analog processing element at a transmission end, and transmits the satellite signal through the waveguide to the waveguide input end.

However, when the high-frequency satellite communication transceiver device receives satellite signals, it needs to eliminate the signal in the vertical polarization direction of the desired satellite signal to avoid the normal operation of the high-frequency satellite communication transceiver device. Therefore, in the known high-frequency satellite communication transceiver, there is also a receiver load termination, which is used to eliminate the reflected signal of the received satellite signal on the receiver load termination. This device can eliminate the signal in the vertical polarization direction of the desired received satellite signal.

However, when the high-frequency satellite communication transceiver device transmits signals, part of the transmitted signals will pass through the terminal element at the receiving end, which will cause energy loss of the transmitted signals, thus resulting in a decrease in the quality of the transmitted signals. Therefore, it is necessary to design a function in the terminal element at the receiving end to avoid the energy loss of the transmitted signal.
