Abstract :
Two thin-film millimeter-wave subassemblies, a 35-GHz low-noise downconverter and an 18- to 40-GHz dual-channel downconverter, are described. The hermetic portion of the 35-GHz downconverter subassembly provides four different circuit functions in a package 1.90-in by 0.75-in by 0.32-in. The dual-channel downconverter subassembly uses three hermetic packages interfaced with small rigid coaxial interconnections. Collectively, these three packages provide five different circuit functions in a total volume of 1.08 cu in. These downconverter subassemblies consist of thin-film circuits which offer reduced system size and low interconnection losses.<>
