Introduction

GDM0628 is a three-stage HBT general purpose power amplifier working at 617~652 MHz (Band 71, N71) with onchip PA enable controller and temperature compensation circuits. This high-efficiency and DPD-friendly PA can deliver up to 28dBm average output power and 37dBm peak power using 20MHz LTE signal (8.5dB PAR @0.01% CCDF). The product input and output are both internally matched to 50Ohm.
