The invention provides a transceiving device for a wireless communication system and communication equipment. The transceiving device comprises a first power divider, a first frequency selection module, a frequency conversion module, a frequency divider, a microcontroller, a frequency synthesizer and a first power amplifier, the first power divider is used for dividing an input initial signal into two paths of signals; the first frequency selection module is used for filtering an input signal to generate a first frequency signal input into the frequency conversion module; the frequency conversion module is used for performing frequency mixing on the first frequency signal and the local oscillation signal output by the first power amplifier, performing up-conversion or down-conversion processing and outputting a frequency mixing signal; the frequency divider is used for carrying out frequency reduction processing on the input signal to obtain a second frequency signal and outputting the second frequency signal to the microcontroller; and the microcontroller is used for judging the receiving and transmitting state of the initial signal according to the second frequency signal and controlling the frequency synthesizer to output the local oscillation signal to the input end of the first power amplifier based on the receiving and transmitting state. The transceiving device is high in integration degree and small in size.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a transceiver and communication equipment used in a wireless communication system. Background technique [0002] As an integral part of the wireless communication system, the frequency mixing device is required for the transceiver channel and equipment self-test in the wireless communication system. The generalization of frequency mixing equipment is the key to realize the miniaturization and light weight of wireless communication system equipment. Especially in the military field, the demand for miniaturization and light weight of wireless communication system equipment is higher than that in the civilian field. In the traditional wireless communication system, the frequency mixing method is to separately design the mixer for the wireless communication system transceiver channel and equipment self-test, which brings design costs, and for the transceiver channel, ...
