General Description
Features
Functional Diagram
High Isolation: 60 dB @ 1 GHz
50 dB @ 2 GHz
Positive Control: 0/+5V
Input IP3: 51 dBm
Non-Re ective Design
Ultra Small MSOP-86 Package: 14.8 mm2
Typical Applications
The HMC435MS8G(E) is ideal for:
• Basestations & Repeaters
• Cellular/3G and WiMAX/4G
• Infrastructure and Access Points
• CATV/CMTS
• Test Instrumentation
The HMC435MS8G(E) is a non-re ective 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 +31 dBm. On-chip circuitry allows
positive voltage control of 0/+5 Volts at very low DC
currents.

Pin Descriptions
Pin Number Function Description Interface Schematic
1 A See truth and control voltage tables.
2 B See truth and control voltage tables.
3, 5, 8 RFC, RF1, RF2 These pins are DC coupled and matched to 50 Ohms.
Blocking capacitors are required.
4N/C
The pins are not connected internally; however, all
data shown herein was measured with these pins
connected to RF/DC ground externally.
6, 7 GND Package bottom has exposed metal paddle that must
be connected to PCB RF ground as well.
Evaluation PCB
The circuit board used in the application should
be generated with proper RF circuit design tech-
niques. 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.
