HSMS-286x Series
Surface Mount Microwave
Schottky Detector Diodes
Data Sheet
Description
Avago’s HSMS-286x family of DC biased detector diodes
have been designed and optimized for use from 915
MHz to 5.8 GHz. They are ideal for RF/ID and RF Tag
applications as well as large signal detection,
modulation, RF to DC conversion or voltage doubling.
Available in various package configurations, this family
of detector diodes provides low cost solutions to a wide
variety of design problems. Avago’s manufacturing
techniques assure that when two or more diodes are
mounted into a single surface mount package, they are
taken from adjacent sites on the wafer, assuring the
highest possible degree of match.
