Functional Diagram
General Description
The HMC550A and HMC550AE 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 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.
