HMC637 Gallium Arsenide Power Amplifiers

Analog Devices’ MMIC for aviation, industrial, and test equipment applications

Image of Analog Devices HMC637 Gallium Arsenide Power AmplifiersADI’s HMC637 is a gallium arsenide (GaAs) cascode distributed power amplifier. This device is a monolithic microwave integrated circuit (MMIC) and contains a pseudomorphic high electron mobility transistor (pHEMT). This power amplifier is self-biased in normal operation and features optional bias control for quiescent current (IDQ) adjustment and second-order intercept (IP2) and third-order intercept (IP3) optimization. The amplifier operates from dc to 7.5 GHz, providing 15.5 dB of small signal gain, 28 dBm output power at 1 dB gain compression, a typical output IP3 of 39 dBm, and a 3.5 dB noise figure, while requiring 345 mA from a 12 V supply voltage (VDD). Gain flatness is excellent from dc to 7.5 GHz at ±0.5 dB typical, making the HMC637 ideal for aviation, industrial and test equipment applications. The HMC637 also features inputs/outputs (I/Os) that are internally matched to 50 Ω, housed in a RoHS compliant, 5 mm × 5 mm, lead frame chip scale package (LFCSP).
