General Description
Absolute Maximum Ratings
Mimix Broadband’s four stage 36.0-43.0 GHz GaAs
MMIC buffer amplifier has a small signal gain of 24.0
dB with a noise figure of 4.0 dB across the band. Gain
increases with frequency to compensate for other
component roll-off factors common in 38.0-40.0 GHz
systems.This MMIC uses Mimix Broadband’s 0.15 µm
GaAs PHEMT device model technology, and is based
upon electron beam lithography to ensure high
repeatability and uniformity.The chip has surface
passivation to protect and provide a rugged part with
backside via holes and gold metallization to allow
either a conductive epoxy or eutectic solder die
attach process.This device is well suited for
