We report the design and evaluation of a broadband, balanced mixer for 100-140 GHz using a HEMT MMIC process on a 75 µm InP substrate. The circuit uses Schottky diodes as mixing elements. It demonstrates a conversion loss of 15 ± 2 dB from 100-130 GHz with 5 dBm LO drive at 80 GHz, Measurements indicate a wide IF bandwidth extending beyond 50 GHz. This is the first demonstration of a monolithic HEMT diode balanced mixer in this frequency range.
