SPDT NON-REFLECTIVE

SWITCH, DC - 4.0 GHz

Typical Applications

Features

The HMC435MS8G / HMC435MS8GE is ideal for:

• Basestation Infrastructure

• MMDS & 3.5 GHz WLL

High Isolation: 60 dB @ 1 GHz

50 dB @ 2 GHz

Positive Control: 0/+5V

51 dBm Input IP3

• CATV/CMTS

Non-Reﬂective Design

MS8G SMT Package, 14.8 mm²

• Test Instrumentation

Functional Diagram

General Description

The HMC435MS8G & HMC435MS8GE are non-

reﬂective DC to 4 GHz GaAs MESFET SPDT switches

in low cost 8 lead MSOP8G surface mount packages

with exposed ground paddles. The switch is ideal

for cellular/PCS/3G basestation applications yielding

50 to 60 dB isolation, low 0.8 dB insertion loss and

+50 dBm input IP3. Power handling is excellent

up through the 3.5 GHz WLL band with the switch

offering a P1dB compression point of +31 dBm. On-

chip circuitry allows positive voltage control of 0/+5

Volts at very low DC currents.

Evaluation PCB

List of Materials for Evaluation PCB 105143 ^[1]

The circuit board used in the ﬁnal 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.
