HMC318MS8GE

Product Overview

HMC318MS8GE is a Hittite / Analog Devices microwave MMIC amplifier from Analog Devices. In an RF design it is normally used as a microwave gain, driver or power-amplifier stage, so the useful sourcing checks are not only the ordering code but also the operating band, gain behavior, output level, package footprint and bias conditions.

For this model, the key application data to verify are: GHz-band microwave coverage is exact-base specific; many HMC/ADPA parts are narrowband or broadband MMICs; gain, Psat/P1dB, OIP3 and NF must be matched to the exact HMC/ADPA base; and positive/negative gate or drain bias as specified by the MMIC family. Because RF amplifier parts are layout- and matching-sensitive, HMC318MS8GE should be treated as an exact-BOM item unless the replacement has been validated with the same matching network, thermal design and control conditions.
