Packaged millimetric multiplier has MMIC multiplier chips on microstrip substrate ceramic circuits with conducting tuning cover and electromagnetic output coupling.

摘要

A packaged millimetric multiplier has an MMIC (Monolithic Microwave Integrated Circuit) multiplier chip (22) with electromagnetically coupled (36) main frequency (30) output through a hole (32) in the metal base (20) under a quarter wave multiple (H) short circuit tuning cover (25) and microstrip sub-harmonic input connection (40) with internal microstrip (26) links on ceramic substrates (24).
