HMC231G7
GaAs MMIC SMT HIGH ISOLATION
SPST SWITCH, DC - 6.0 GHz
Features
Isolation: 55 dB @ 2.0 GHz
42 dB @ 6.0 GHz
Insertion Loss: 2.0 dB Typical @ 6.0 GHz
Non-Refl ective Input/Output
Hermetic Surface Mount Package
General Description
The HMC231G7 is a broadband high isolation
non-refl ective GaAs MESFET SPST switch in a
hermetic surface mount package. Covering DC
to 6.0 GHz, the switch features >55 dB isolation
up to 2 GHz and >42 dB isolation up to 6.0 GHz.
The switch operates using complementary
negative control voltage logic lines of -5/0V and
requires no bias supply. When the “OFF” state is
selected, both RF1 and RF2 ports are terminated
in 50 Ohms.

* Circuit Board Material: Rogers 4350
The circuit board used in the fi nal 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 package bottom 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.
