Abstract :
A monolithic microwave integrated circuit (MMIC) W-band varactor doubler that delivers 30 mW of output power at 93 GHz with 12% conversion efficiency has been developed U-band MMIC MESFET power amplifier chips that exhibit 0.23 W of output power with 13 dB from 45.5 to 46.5 GHz were also developed. A doubler/amplifier chain has been integrated to deliver 30 mW of output power at 93 GHz with an overall gain of 7 dB.<>
