General Description
The HMC550 and HMC550E are low-cost SPST
Failsafe switches in 6-lead SOT26 plastic packages
for use in switching applications which require low
insertion loss and very low current consumption. With
0.7 dB typical loss, these devices can control signals
from DC to 6.0 GHz and are especially suited for IF
and RF applications including RFID, ISM, automotive
and battery powered tags and portables. RF1 and RF2
are reflective opens when “Off”. The switch requires a
minimal amount of DC current in the “On” state, and
offers compatibility with CMOS and some TTL logic
families. The failsafe topology results in the switch
being normally “On”, i.e. low insertion loss from RF1 to
RF2, when no DC bias is applied.
