Description
These low cost, surface mountable plastic packaged silicon
mixer Schottky diodes are designed for RF and microwave
mixers and detectors.They include low barrier diodes and zero
bias detectors, combining Alpha's advanced semiconductor
technology with low cost packaging techniques. All diodes are
100% DC tested and deliver tight parameter distribution,
minimizing performance variability.They are available in SC-
70, SC-79, SOD-323, SOT-23 and SOT-143 packages.Wiring
configurations include singles, common cathode, series pairs
and unconnected pairs. Applications include low noise
receivers used in high sensitivity ID tags, wireless systems,
radio designs and may be used at frequencies to 10 GHz.
SPICE model parameters are included as a design tool.
