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.

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.
