4.9.

Circuit Operation (RF Part)

General Description:

RF part includes Transmitter and Receiver functions. Digital signals (Mainly voice data) that come from DSP, are modulated and
are transmitted. On the other hand, received signals are demodulated and go out to DSP.

4.9.1.

Power Supply Circuit

As indicated below, the various voltages are supplied to each block.
V_PA, about 4.0 V at base unit or 3.3 V at handset, is supplied to the Power amplifier in 5.8 GHz PA circuit.
IC761 is 3.0 V Regulator and outputs VRF (3.0 V) by order of RADIO_EN signal.
V_RF is approximately 4.0 V (Base Unit) or 3.6 V (Handset).
