A novel K-band Self-Oscillating Mixer based on push-push topology

This paper presents a balanced K-band (18 to 27 GHz) Self-Oscillating Mixer (SOM) with 0.18 ¿m CMOS technology. The proposed SOM employs a push-push configuration for the oscillating function which is designed to operate at K-band. Using the push-push configuration, a K-band frequency of 22.57 GHz is achieved. The proposed SOM uses an RF frequency of 23 GHz, and generates a self-oscillation frequency of 11.28 GHz, a push-push frequency of 22.57 GHz and an IF frequency of 386.3 MHz from a 1.8 V power supply. The proposed SOM has an output power of -46 dBm (Pin = -40 dBm) at IF frequency, the gain of -6 dB and the P1dB of -15 dBm.
