Features
Low Insertion Loss: 0.25 dB
High Input IP3: +65 dBm
Low DC Power Consumption
Positive Control: 0/+3V to 0/+8V
Ultra Small Package: SOT26
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
www.DataSheet4U.ceomxceptional 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.

Notes:
1. Set logic gate Vdd = +3V to +5V and use HCT series logic to provide a TTL driver interface.
2. Control inputs A/B can be driven directly with CMOS logic (HC) with Vdd of +3V to +8V applied to the CMOS logic gates.
3. DC Blocking capacitors are required for each RF port as shown. Capacitor value determines lowest frequency of operation.
4. Highest RF signal power capability is achieved with Vdd = +8V and A/B set to 0/+8V.
