Abstract

This paper reports on a 20 to 40 GHz monolithic double-balanced mixer implemented using InGaP/GaAs HBT process The compact MMIC mixer makes use of a Gilbert-cell multiplier with broadband input matching networks to widen the bandwidth up to 20 GHz. Operated as a down-converter mixer,a measured conversion gain of 16 dB was achieved given an RF signal at 30 GHz,LO drive of 5 dBm and a down- converted baseband signal at 10 MHz.The mixer IP3 occurs at an output power of 4 dBm while the IP2 occurs at an output power of 11 dBm.The developed mixer presents an attractive building block for future high data rate systems employing direct-digital modulators/demodulators.
