• Temperature compensation of sensor signal
• Active filter for Digital-to-Analog Converter (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)
• Compatible with a wide range of silicon PAs
• Compatible with multislot class 12
• Dual output with internal switch
• Two different transfer functions
• Possibility to adapt dynamic transfer functions
• Very small outline package (3 × 3 mm).

APPLICATIONS
• Global System for Mobile communication (GSM)
• Personal Communications Network (PCN) systems.
