Distributed 1-w Power Amplifier Covers Dc To 6 Ghz

摘要

Hittite Microwave Corporation has released chip and SMT GaAs pHEMT MMIC power amplifiers, designated HMC637 and HMC637LP5 respectiveley, which are ideal for military EW, test & measurement equipment, and telecom applications from DC to 6 GHz.rnThe HMC637 is a GaAs pHEMT MMIC power amplifier chip that is rated from DC torn6 GHz, and delivers 14 dB gain, +30 dBm saturated output power, and +41 dBm output IP3. The power amplifier also delivers consistent output IP3 and excellent gain flatness of ±0.6 dB across its rated bandwidth. This versatile power amplifier chip requires no external matching components, occupies an area of 7.3 mm~2, and consumes only 400 mA from a +12 V supply.
