Functional Diagram
General Description
The HMC545 and HMC545E are low-cost SPDT
switches in 6-lead SOT26 plastic packages for use
in general switching applications which require
very low insertion loss and very small size. With
0.25 dB typical loss, these devices can control sig-
nals from DC to 3.0 GHz and are especially suited
for IF and RF applications including Cellular/3G,
ISM, automotive and portables. The design provides
exceptional insertion loss performance, ideal for filter
and receiver switching. RF1 and RF2 are reflective
shorts when “Off”. The two control voltages require a
minimal amount of DC current and offer compatibility
with CMOS and some TTL logic families.
