　　General Description

　　The TQM7M5013 is an input power controlled， multiple gain state， quad band， GSM/EDGE PAM designed for use with the Qualcomm QTR/RTR8600 WEDGE solutions. This highly efficient PAM significantly improves talk-time while still providing an easy to use solution in a small form factor. The PA output power is controlled by the input power coming from the transceiver in both GMSK and 8PSK modes and so does not require a Vramp input. Additionally， the small 5 mm x 5 mm package requires minimum board space and allows for high levels of phone integration.
