Typical Applications

The HMC545 / HMC545E is ideal for:

• Cellular/3G Infrastructure

• Private Mobile Radio Handsets

• WLAN, WiMAX & WiBro

• Automotive Telematics

• Test Equipment

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.
