Description
Avago’s HSMS‑286x family of DC biased detector diodes
have been designed and optim ized 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 con figurations, 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.
