Its application has been extended to various standards in the field of mobile cellular communication, such as global satellite navigation system, wireless local area network and wireless sensor network, so it is necessary to study and design wireless radio frequency transceiver compatible with various communication standards. Low noise amplifier (LNA) is the first active module in the receiver. In the multimode and multi-standard receiver, its wideband anti-blocking ability has a great influence on the multi-mode multi-frequency receiver.
