This letter describes a novel mixer fabricated using a unique low-cost
approach to achieve effective conversion performance, By utilizing hi
p-chip GaAs Schottky diodes mounted on a duroid substrate, this radio
frequency (RF) probeable mixer achieves 11,3-dB conversion loss at 77
GHz with an IF frequency of 500 MHz, This new technology demonstrates
an affordable alternative to standard millimeter-wave circuit fabricat
ion while offering the capability to integrate a variety of device tec
hnologies in the same circuit.
