GaAs MMIC Diode Technology Enables High Linearity and Low Power

摘要

In this article, we discuss MMIC mixers designed using high performance GaAs Schottky diodes. Compared to fixed Schottky diode options already on the market, we describe, for the first time, GaAs diodes with forward voltages ranging from 0.29 to 0.9 V. These diodes enable new Circuit capabilities previously not possible in GaAs diode circuits. A state-of-the-art MMIC mixer has been developed and new performance characteristics demonstrated, including low LO drive for power sensitive applications and high LO drive for high linearity applications.
