3.1 Receiver

The receiver part contains all active circuits for a complete, full receiver chain with the exception of
RF PLL VCO(U302) and discrete RF SAW filters. The filtered and amplified signal is processed from
the RF-mixer inputs to the baseband(BB) output. The receiver path is supported by external channel
filtering. The RF front-end circuit is shown Fig. 3-1.
