Transmit modes should always use fø = 200kHz. The IF and RF output frequencies are set by
programming he N-Divider registers and also programmed via 3-wire interface with external system
controller.

3.3 Transmitter Part
The Transmitter part contains the transmitter parts of Si4205-BM[U803], Power Amp Module[U804]
and Antenna switch[FL801]. The transmit section of Si4205-BM [U502] consists of an I/Q baseband
upconverter, an offset phase-locked loop(OPLL) and two output buffers that can drive external power
amplifiers(PA).
The RF GMSK outputs from the transmit VCO are fed directly to the RF power amplifiers.
The peak output power and the profile of the transmitted burst are controlled by means of
incorporated power control circuits inside of PA and DAC output from the Baseband Controller.
The PA outputs pass to the antenna connector via Antenna Switch.
