A 1 watt, 3.2 VDC, high efficiency distributed power PHEMT amplifier fabricated using LTCC technology

A 1 watt distributed PHEMT amplifier, that operates from 800 MHz to 2.1 GHz, with a 3.2 Volt DC supply has been developed using a novel new approach. The amplifier was designed to provide high efficiency operation, targeted for broadband wireless applications. Key to the amplifier's performance, is a novel broadband impedance matching transformer, fabricated using LTCC technology, as well as a low loss tapered drain network. The class B design has 50 /spl Omega/ terminal impedances and built-in bias decoupling.
