Design and Performance of A Novel Balanced Self-Oscillating Mixer

A balanced self-oscillating mixer has been fabricated and tested. By utilising the symmetrical configuration technique, the circuit provides anti-phase output signals. Its inherent mixing is given by the non-linear mechanism of an active device. Therefore, anti-phase intermediate frequency performance has been investigated. In addition, the RF port is taken into account in order to obtain conversion gain. Unlike the typical mixer, the balanced self-oscillating mixer can achieve smaller size and consume less power.
