General Description
The HMC1055LP2CE is low-cost SPST Failsafe
switch in 2x2mm,8 lead DFN plastic package for
use in switching application which require low
insertion loss and very low current consumption.
With 0.7 dB typical loss, these devices can control
signals from DC to 4 GHz and are especially suited
for IF and RF applications including RFID, ISM,
automotive and battery powered tags and portables.
RF1 and is reflective open while RF2 is terminated in
50 OHMs 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.
