RF introduction

The RF is controlled by digital baseband circuitry via a serial bus (RFBus). The RFBus is for mode selection,
frequency synthesizer control, RX AGC setting, RF regulator control, TX power control loop and PA bias control.
In addition to RFBus there are also several other interface signals coming from BB. TX power control (TXC),
VCTCXO frequency control (AFC) and some other control signals (voltage and current references, WCDMA TX
power detection, PA combination detection).
