Abstract

We present the design and development of a K-band surface mount package for ~10 Watt DC power dissipation devices. The package forms a near hermetic cavity enclosed by liquid crystal polymer (LCP) and copper. The measured junction temperature of ~10 Watt DC power dissipation is 143.9°C with the base plate at 80°C. The package feedthrough achieves a measured insertion loss of ~0.5 dB to 0.8 dB at K-band frequencies.
