HSMS-285x Series
Surface Mount Zero Bias Schottky Detector Diodes
Data Sheet
Description
Avago’s HSMS-285x family of zero bias Schottky detector
diodes has been designed and optimized for use in small
signal (Pin <-20 dBm) applications at frequencies below
1.5 GHz. They are ideal for RF/ID and RF Tag applications
where primary (DC bias) power is not available.
Important Note:
power levels greater than –20 dBm, use the HSMS-282x
series at frequencies below 4.0 GHz, and the HSMS-286x
series at frequencies above 4.0 GHz. The HSMS-285x
series IS NOT RECOMMENDED for these higher power
level applications.
Available in various package configurations, these detec-
tor diodes provide low cost solutions to a wide variety
of design problems. Avago’s manufacturing techniques
assure that when two diodes are mounted into a single
package, they are taken from adjacent sites on the wafer,
assuring the highest possible degree of match.
Pin Connections and Package Marking
Notes:
1. Package marking provides orientation and identification.
