TQM7M4007 四频段GSM/GPRS功放模块
The TriQuint TQM7M4007 is an extremely small (5 x 5 x 1 mm) multi-mode power amplifier module for GSM / GPRS applications. This module has been optimized for high GSM / GPRS efficiency. The module incorporates two highly integrated InGaP power amplifier die with a CMOS controller. The CMOS controller implements a fully integrated closed-loop power control within the module for GSM operation. This eliminates the need for any external couplers, power detectors, current sensing or other components to assure the output power level. The latter is set directly from the Vramp input from the DAC. The module has Tx enable and band select. The module construction is a low-profile over-molded land-grid array on a halogen free laminate.
