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 143.9oC with the base plate at 80oC. The package feedthrough achieves a measured insertion loss of ∼ 0.5 dB to 0.8 dB at K-band frequencies.
