Abstract :
This paper presents a broadband and compact SiBJT balanced up-converter MMIC using Si 3-D MMIC technology. The balanced up-converter consists of newly designed Marchand-type balun, and two unit mixers that have stacked matching circuits. The fabricated balanced upconverter MMICs occupies just 1 mm/sup 2/ but achieves a conversion gain of 2.5 dB/spl plusmn/2.5 dB and LO signal suppression of more than 30 dB at an RF port from 12 GHz to 27 GHz. The power consumption is 9.8 mW with 1 V supply voltage. The broadband performance factor of the fabricated MMIC is twice those of previously reported balanced up-converter MMICs.
