Typical Applications
The HMC545A / HMC545AE is ideal for:
• Cellular/3G Infrastructure
• Private Mobile Radio Handsets
• WLAN, WiMAX & WiBro
• Automotive Telematics
• Test Equipment
The HMC545A and HMC545AE 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
signals 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 lter
and receiver switching. RF1 and RF2 are reective
shorts when “Off”. The two control voltages require a
minimal amount of DC current and offer compatibility
with CMOS and some TTL logic families.
