DESCRIPTION

The SD8901 is a ring demodulator/balanced mixer. Designed

to utilize Calogic’s ultra high speed and low capacitance

lateral DMOS process.

The SD8901 offers significant

performance improvements over JFET and diode balanced

mixers when low third order harmonic distortion has been a

problem.
