Abstract :
A balanced HEMT (high electron mobility transistor) doubler for operation at millimeter waves has been analyzed, fabricated, and characterized. Particular attention has been paid to the influence of the output circuit on the performance of the doubler. The doubler was analyzed with a harmonic balance method and an output power of 4 dBm at 42 GHz was obtained experimentally. The conversion gain is approximately -1 dB at 40 GHz at an input power of 5 dBm. Bias and frequency response were very close to the predicted ones.<>
