Abstract

The invention provides a signal receiving and transmitting machine and belongs to the technical field of communication. The signal receiving and transmitting machine at least comprises a local frequency generation module and a frequency source, and the local frequency generation module generates multiple signals of different frequencies according to fixed frequency signals provided by the frequency source. By means of the signal receiving and transmitting machine, the power loss can be reduced.

Description

technical field [0001] The invention relates to a transceiver and belongs to the technical field of communication. Background technique [0002] The mixer and the wave detector in the transceiver in the prior art use different frequency sources respectively, so that the cost and power consumption are increased, and the integration degree is not high, and the volume is relatively large. Contents of the invention [0003] In order to overcome the technical problems in the prior art, the object of the invention is to provide a transceiver with high integration, miniaturization and reduced power loss. [0004] To achieve the purpose of the invention, the present invention provides a transceiver, characterized in that it includes at least a local frequency generation module and a frequency source, and the local frequency generation module generates multiple signals of different frequencies according to the fixed frequency signals provided by the frequency source. [0005] Pref...
