Surface Mount Mixer and Detector Schottky Diodes
Features
s Tight Parameter Distribution s Available as Singles and Pairs s 100% DC Tested s Designed for High Volume Commercial Applications s Available in Tape and Reel Packaging
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 SC70, 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.
