Microwave monolithic integrated circuit (MMIC) having integrated high power thermal dissipating load

摘要

A Microwave Monolithic Integrated Circuit (MMIC) having an integrated high power load. The MMIC includes a microwave transmission line and a resistive load coupled to a terminating end of the microwave transmission line. The resistive load comprises a hollow resistive material disposed on sidewalls of a via passing through a substrate, the resistive material having an upper portion electrically connected to a terminating end of a strip conductor of the microwave transmission line strip conductor and a lower portion electrically connected to the ground plane.
