摘要

Cryogenic Low Noise Amplifiers, based on MMIC HEMT technology, require a careful packaging to reach optimalperformance. Differences between modeled and measured performance can often be related to chip mounting details. Inthe framework of the development of new cryogenic LNAs, described in a companion paper, we have developed aspecific packaging to host W-band cryogenic MMIC LNAs. We present here some of the main factors analyzed in thedesign and chip integration activities. In particular, mechanical and thermal modeling, LNA chip gluing and adhesiveproperties, sensitivity to components integration accuracy (i.e. deviation from the ideal orientation). Preliminary testresults are also reported.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE). Downloading of the abstract is permitted for personal use only.
