RF Front-end Design of Multiplex Link Transceiver

Jing Bao

Abstract

In order to increase the anti-jamming capabilities and save power and size of the transceiver,the RF front-end of multiplex link frequency-hopping transceiver for portable frequency hopping radio is designed.Both the transmitter and receiver links in the design use the twice frequency conversion,and their output and input frequencies are continuously variable in between 110MHz and 512MHz.Finally,the test on the RF front-end performance is done,and the results show that this RF front-end meets all the goal requirements of low noise,low spur,small ripple in band and fast frequency hopping.
