A direct conversion receiver IC including an on-chip balun, an I/Q mixer, a variable gain amplifier and a 90° phase-shifter is fabricated in a Bi-CMOS technology with 15 GHz transition frequency (f_T). This paper demostrates that cascaded connection of an on-chip balun and a double balanced mixer as the I/Q mixer is effective to achieve a low DC offset and a low second-order distortion, on the basis of both careful examination of the mixer behavior and measurement. Input-referred DC offset voltage of less than 300 μV and spurious free dynamic range (SFDR) of over 67 dB are obtained by measurement. The IC consumes 52 mA arom 2.7V power supply voltage. The die size is 3mm × 3mm.
