v01.1009
HIGH ISOLATION SPDT
NON-REFLECTIVE SWITCH, DC - 6 GHz
Typical Applications
The HMC849LP4CE is ideal for:
• Cellular/4G Infrastructure
• WiMAX, WiBro & Fixed Wireless
• Automotive Telematics
• Mobile Radio
• Test Equipment
Features
High Isolation: up to 60 dB
Single Positive Control: 0/+3V to +5V

Functional Diagram
General Description
The HMC849LP4CE is a high isolation non-reflec-
tive DC to 6 GHz GaAs pHEMT SPDT switch in a low
cost leadless surface mount package. The switch is
ideal for cellular/WiMAX/4G Infrastructure applicati-
ons yielding up to 60 dB isolation, low 0.8 dB inser-
tion loss and +52 dBm input IP3. Power handling
is excellent up through the 5 - 6 GHz WiMAX band
with the switch offering a P1dB compression point of
+31 dBm. On-chip circuitry allows a single positive
voltage control of 0/+3V or 0/+5V at very low DC
currents. An enable input (EN) set to logic high will put
the switch in an “all off” state.

* The RF input power is quite lower than the breakdown
power levels. Hence, the only concern with this product
is the thermal limit.
