Quad-Band GSM/GPRS PA Module with integrated Power Control

The MMM6035 is a 50-ohm Power Amplifier module for quad-, tri-, and dual-band GSM handset applications, functioning over the GSM850, EGSM, DCS, and PCS frequency bands. This module is compatible with GSM/GPRS operating modes (up to 50% duty cycle). To simplify radio front-end design requirements, the power control function is integrated, removing the need for directional couplers and detector diodes. GSM burst shaping and power control is integrated on an internal control SmartMOS IC. The analog power control signal is smoothed by a low-pass filter included in the internal control SmartMOS chip, allowing over 45 dB dynamic range to be achieved.
