18.0 to 38.0

Mimix Broadband’s three stage 18.0-38.0 GHz GaAs 
MMIC buffer amplifier has a small signal gain of 21.0 dB 
with a positive gain slope, and a noise figure of 3.2 dB 
across the band. 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 Millimeter-wave 
Point-to-Point Radio, LMDS, SATCOM and VSAT 
applications.
