摘要：
A 45-GHz single-ended HEMT mixer has been developed with unity gain and 7-8-dB single-side-band noise figure over a 2-GHz bandwidth. The mixer includes an IF amplifier, and has a 2-dBm output intermodulation intercept. The mixer's design, structure, and performance are described. High performance has been achieved by careful attention to the design of the input and output embedding networks. This is the first reported HEMT mixer and the first active mixer above 30 GHz. Its performance compares favorably with that of diode mixers with less local oscillator power in an inexpensive, reliable, microstrip circuit.
