Problems solved by technology

In the process of frequency shifting, if the local oscillator sources of the microwave relay transceiver unit are not equal, it will cause the frequency deviation of the communication radio frequency signal
[0011] 4. The uncertainty of the link loss of the microwave relay transceiver unit of the microwave relay system and the instability of the received power level
[0012] 5. The operating frequency of digital microwave transceivers is getting higher and higher, and its passband is getting wider and wider. In such a wide frequency range, the performance differences of devices at different frequencies are prominent, making it difficult to control the final output power of the transmitter. In the case of different transmission frequencies, the transmission power deviates greatly

Description

technical field [0001] The invention relates to the field of microwave communication, in particular to a microwave frequency hopping transceiver. Background technique [0002] In mobile communication systems, repeaters are generally used as relay equipment for base station signal or mobile terminal signal transmission. The repeater first amplifies the forward communication signal of the base station or the reverse communication signal of the mobile terminal, and then forwards the amplified reverse or forward communication signal, so that the function of the base station can be realized at a relatively low cost Enhanced, the coverage of mobile communication signals is further enhanced. [0003] The repeater transceiver is generally composed of a base station (near-end) duplexer, a forward amplification module, a reverse amplification module, and a mobile (far-end) duplexer. Among them, the forward link is composed of the near-end duplexer, the forward amplification module, ...
