Features: brand new and high quality The AD834 four-quadrant analog multiplier is an important component of modern signal processing systems and is widely used in phase-locked loops. In the signal processing power of mixers, filters, etc., its working bandwidth has exceeded 500MHZ. It is the most widely known analog multiplier with the working bandwidth. The AD834 module's rear-stage output adopts the differential balun to single-ended structure. Effectively suppresses harmonics and works well for differential merging, making the output signal symmetrical.
