TQM7M5005H 四波段GSM/GPRS/EDGE-线性功率放大器模块
The TriQuint TQM7M5005H is an extremely small (5 x 5 x 1 mm) multi-mode power amplifier module for GSM / EDGE applications. This module has been optimized for high EDGE efficiency and EDGE power class E2 operation while maintaining 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, band select, mode (EDGE or GSM) inputs. The module construction is a low-profile over-molded land-grid array on a halogen-free laminate.
