Abstract :
Using a high-resistivity substrate SiGe HBT process by Daimler-Benz, MMIC oscillators with 3 dBm output power at 38 GHz as well as a 26 GHz amplifier and a 77 GHz diode mixer were fabricated. This demonstrates the potential of silicon-based ICs even for the millimeter-wave frequency range. The circuit concept follows the classical microwave design approach applying reactive matching on input and output. Coplanar design yields cost reduction compared to the microstrip case because backside processing is not necessary.
