Surface-mount Schottky Mixer and Detector Diodes
These quad devices are available in low, medium and high barrier designs; and as ring, crossover and bridge quads, and octoquad rings in industry-standard SOT-143 packages. These quad configurations are designated for use as low noise figure, wide dynamic range, double-balanced mixers and modulators in high volume wireless applications. The surface-mount Schottky diodes are 100 percent DC tested and deliver tight parameter distribution, minimizing product performance variability. Price: 17¢ for the model SMS 1546-001 low barrier detector and mixer diode (12,000).
