Typical Applications
The HMC544 / HMC544E is ideal for:
· Cellular/PCS/3G Infrastructure
· Basestations & Repeaters
· WLAN, WiMAX and WiBro
· Microwave and Fixed Wireless Radios
The HMC544 & HMC544E are low cost SPDT switches
in 6-lead SOT26 packages for use in transmit-receive
applications which require very low insertion loss
at medium power levels. These devices can control
signals from DC to 4.0 GHz and are especially suited
for 450, 900, 1900, 2300, and 2700 MHz applications
with <0.5 dB insertion loss. This GaAs PHEMT design
provides exceptional linearity performance of +36
dBm 1dB compression point and +55 dBm third order
intercept at +3 volt bias. RF1 and RF2 are refl ective
opens when "Off". On-chip circuitry allows positive
control operation at very low DC current.

Typical Application Circuit
Pin Descriptions
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 +5V 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.
