Functional Diagram
General Description
The HMC233G8 is a broadband high isolation non-
reflective GaAs MESFET SPDT switch in a hermetic
surface mount package. Covering DC to 6.0 GHz, the
switch features >44 dB isolation up to 2 GHz and >31
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.

The circuit board used in the final 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
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.
