B11G2327N71DYZ

Overview

The B11G2327N71D is a dual-section, two-stage fully integrated Doherty Monolithic Microwave Integrated Circuit (MMIC) utilizing Ampleon LDMOS technology. Designed for the 2300 MHz to 2700 MHz frequency range, it integrates carrier and peaking devices, input splitters, output combiners, and pre-matches within each section. The device operates with a drain-source voltage of 28 V and delivers an output power at 1 dB gain compression (PL(1dB)) of 49.5 dBm at 2500 MHz. It achieves a typical power gain of 30.3 dB and a drain efficiency of 20.7% under W-CDMA test conditions. The package is PQFN-12x7-36-1.
