The receive section interfaces between the RF band-select SAW filters and the baseband subsystem. The Si4209 receiver leverages a proven digital low-IF architecture and enables a universal baseband interface without the need for complex dc offset compensation. The transmit section of Si4209 provides a complete upconversion path from the baseband subsystem to the power amplifier (PA) using an offset phase-locked loop (OPLL) integrated with Silicon Laboratories’ patented synthesizer technology.
