Abstract

A single-FET active balun has been developed with a phase imbalance of less than +/- 1.5 degrees and amplitude imbalance less than +/- 0.6dB from 4 to 8 GHz using 0.25 mu m silicon-on-sapphire CMOS. The source terminal of the transistor has been compensated with a shunt capacitance to ground and increased value for the source resistance. The compensation network has improved the phase imbalance by 29 degrees at 8 GHz. The circuit dissipates 15mW and is 260x300 mu m including AC coupling capacitors.
