The operation of the transceiver is illustrated in Figure 2.16 on page 53.
These block diagrams show the hardware modules integrated with the
software modules:
■ hardware (transmitter, receiver, CODEC and audio)
■ RISC processor (on FPGA of digital board)
■ custom logic (on FPGA of digital board)
■ DSP block (on digital board).
The transmit path consists of three major functional parts:
■ audio processing and signalling
■ frequency synthesizer
■ RF transmitter.
