Abstract
Embodiments of the present disclosure disclose a wireless transceiver. The wireless transceiver includes a second control switch, and the second control switch may selectively connect a signal output end of a coupler or a signal output end of a low noise amplifier LNA to a signal input end of the down converter. Therefore, when the signal output end of the coupler is connected to the down converter, the coupler, the down converter, and the analog-to-digital converter ADC form an observer; when the second control switch connects the signal output end of the low noise amplifier LNA to the signal input end of the down converter, a transceiver antenna, the low noise amplifier LNA, the down converter, and the analog-to-digital converter ADC form a receiver. Therefore, the embodiments of the present disclosure can greatly save hardware costs of a system for implementing an observer circuit.
