Introduction

GDM1828 is a three-stage HBT general purpose power amplifier working at 1805~1880MHz (band 3) with on-chip 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 (9.5dB PAR @ 0.01% CCDF). The product input and output are both internally matched to 50ohm.
