Introduction

The AGR18125E is a 125 W, 26 V, N-channel gold-metallized, laterally diffused metal oxide semiconductor (LDMOS) RF power field effect transistor (FET) suitable for global system for mobile communication (GSM), enhanced data for global evolution (EDGE), and multi-carrier class AB power amplifier applications. This device is manufactured using advanced LDMOS technology offering state-of-theart performance and reliability. It is packaged in an industry-standard package and is capable of delivering a minimum output power of 125 W which makes it ideally suited for today’s RF power amplifier applications.
