SPDT SWITCH, DC - 6 GHz
v00.0504
General Description
Features
Functional Diagram
The HMC233G8 is a broadband high isolation non-
re ective GaAs MESFET SPDT switch in a hermetic
surface mount package. Covering DC to 6 GHz, the
switch features >44 dB isolation up to 2 GHz and
>31 dB isolation up to 6 GHz. The switch operates
using complementary negative control voltage logic
lines of -5/0V and requires no bias supply.
Isolation: 44 dB @ 2.0 GHz
31 dB @ 6.0 GHz
Insertion Loss: 1.5 dB Typical @ 4.0 GHz
Non-Re ective Design
Hermetic Surface Mount Package
Electrical Speci cations, TA = +25° C, With 0/-5V Control, 50 Ohm System
Typical Applications
The HMC233G8 is ideal for:

Evaluation PCB
The circuit board used in the nal 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.
