Abstract
A 44-GHz doubler was designed and fabricated using 100- mu *0.15- mu m InGaAs high-electron-mobility transistor (HEMT) and microwave integrated circuit (MIC) circuit. The doubler shows a minimum conversion loss of 1.4 dB with 0.4-dBm output power and 1.6-dBm maximum output power with 3.4-dB conversion loss. A 44-GHz InGaAs HEMT doubler-amplifier chain was also fabricated, demonstrating 10-dBm power, 7-dB overall gain, and 2-GHz bandwidth at the output frequency.<>
