Philips Electronics 

Philips Semiconductors

Power amplifier controller for GSM and

PCN systems

Product specification

PCF5078

FEATURES

• Compatible with baseband interface family PCF5073x

• Two power sensor inputs

• Temperature compensation of sensor signal

• Active filter for DAC input

• Power Amplifier (PA) protection against mismatching

• Bias current source for detector diodes

• Generation of pre-bias level for PA at start of burst

(home position)

• Possibility to adapt home position by external

components

• Applicable for a wide range of silicon and GaAs power

amplifiers.

APPLICATIONS

• Global System for Mobile communication (GSM)

• Personal Communications Network (PCN) systems.

GENERAL DESCRIPTION

This CMOS device integrates an amplifier for the detected

RF voltage from the sensor, an integrator and an active

filter to build a PA control loop for cellular systems with a

small amount of passive components.
