Resistive Blanced Audio Mixer

1. The principle of resistive mixers

The most used device for the resistive mixer is the Schottky diode, it can be used up to THz-frequencies. The FET-based resistive mixer is an interesting alternative if 1. generation of intermodulation products is critical 2. FET/HEMT based MMIC designs are considered 3. LO and RF are close together and large bandwidth is required +-V D I D =I ...

A simple balanced-mixer circuit that uses the resistive channel of a GaAs MESFET exhibits superior intermodulation performance, with other performance parameters, e.g., conversion loss, port impedances, and LO sensitivity, being equal to or better than other diode mixers.

resistive) and the bias current. The reader is referred to [1] for excellent analysis of mixer G m linearity. Inductive degeneration is widely used for its low noise and the higher linearity it provides compared to resistive or capacitive degeneration. In highly degenerated input G m cells with relatively large bias current, the mixer linearity will be limited
