Surface Mount Mixer and
Detector Schottky Diodes
Features
Designed for High Volume Commercial
Applications
Available Lead (Pb)-Free MSL-1 @ 250C
per JEDEC J-STD-020
Tight Parameter Distribution
Available as Singles and Pairs
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 Skyworks'
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,
SOT-143, and LGA 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.
