Product Description
The TQM 7M5004 is an extremely small (7x7x1.1mm
3
) 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. Two EDGE quiescent current states are provided to minimize current
consumption during backed-off power settings.
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 etc., to assure the output power level. The
latter is set directly from the V
ramp
input from the DAC. The module has Tx enable,
band select, mode (EDGE or GSM) inputs. Module construction is a low-profile over-
molded land-grid array on laminate.
