A simple dual-balun structure is proposed for a
miniature monolithic microwave integrated circuit (MMIC) double
doubly balanced mixer (DDBM) design. The dual balun is
realized by using two out-of-phase power splitters in parallel,
which are then applied in a DDBM mixer. The measured conversion
loss of the mixer is less than 10 dB for a radio frequency
(RF) bandwidth of 2–5.5 GHz and fixed intermediate frequency
(IF) output frequency of 2 GHz. The mixer achieves a high input
IP3 of 24 dBm and a 1-dB compression input power of 13 dBm
at 17-dBm local oscillator (LO) drive. The chip area of mixer is
less than 1.0 1.4 mm2, which is the smallest size ever reported
for monolithic DDBM mixers.
