SPDT NON-REFLECTIVE
SWITCH, DC - 4 GHz
General Description
Features
Functional Diagram
High Isolation: 62 dB @ 1 GHz
52 dB @ 2 GHz
Single Positive Control: 0/+5V
Input IP3: 54 dBm
Non-Reective Design
Ultra Small MSOP-86 Package: 14.8 mm2
Typical Applications
The HMC435AMS8G(E) is ideal for:
• Basestations & Repeaters
• Cellular/3G and WiMAX/4G
• Infrastructure and Access Points
• CATV/CMTS
• Test Instrumentation
The HMC435AMS8G(E) is a non-reective DC to
4 GHz GaAs MESFET SPDT switch in a low cost 8
lead MSOP8G surface mount package with exposed
ground paddle. The switch is ideal for cellular/3G and
WiMAX/4G applications yielding up to 60 dB isolation,
low 0.8 dB insertion loss and +50 dBm input IP3. Power
handling is excellent up through the 3.8 GHz WiMAX
band with the switch offering a P1dB compression of
+30 dBm. On-chip circuitry allows positive voltage
control of 0/+5 Volts at very low DC currents.

The circuit board used in the application should
be generated with proper RF circuit design
techniques. Signal lines at the RF port should have
50 Ohm impedance and the package ground leads
and backside ground slug should be connected
directly to the ground plane similar to that shown
above. The evaluation circuit board shown above is
available from Hittite Microwave Corporation upon
request.
