Preliminary specification
Power amplifier controller for GSM and
PCN systems
PCF5077T
Application in mobile stations
Using a directional coupler with 16.5 dB attenuation
produces a sensor signal between 100 mV and 3 V below
the diode forward voltage at pin VS for the PA output
power range of 8 to 36 dBm.
The sensor voltage of 3 V at pin VS corresponds to the
maximum DAC output voltage. The power range that can
be controlled is therefore not limited by the sensor voltage
input VS and higher power levels can be controlled with
the control loop switched on.
