ITEM NAME:AD834 Four Quadrant Analog Multiplier Double Frequency Multiplier 500MHz Description: The AD834 four-quadrant analog multiplier is an important component of modern signal processing systems. Widely used in phase-locked loops, signal processing power of mixers, filters. Working bandwidth exceeded: 0.1-500MHZ. This AD834 module's rear-stage output adopts the differential balun to single-ended structure, can effectively suppresses harmonics and works well for differential merging, making the output signal symmetrical. Power supply voltage: Â ±5V (default configuration) Input impedance: 50 ohms Output impedance: high resistance (can be connected to 50 ohms) Supply current: Â ±30mA Working bandwidth: 0.1-500MHz Size Chart: Overall size: approx. 50x48mm/1.97x1.89inch Package Includes: 1 Piece AD834 Multiplier Module.The AD834 four-quadrant analog multiplier is an important component of modern signal processing systems. 1 Piece AD834 Multiplier Module.
