Description
Hewlett-Packard鈥檚 HSMS-285A
family of zero bias Schottky detector
diodes and the HSMS-286A 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, cellular and
other consumer applications
requiring small and large signal
detection, modulation, RF to DC
conversion or voltage doubling.
Available in various package
configurations, these two families of
detector diodes provide low cost
solutions to a wide variety of design
problems. Hewlett-Packard鈥檚
manufacturing techniques assure
that when two diodes are mounted
into a single SOT-323 package, they
are taken from adjacent sites on the
wafer, assuring the highest possible
degree of match.
