HMC232C8
GaAs MMIC SMT HIGH ISOLATION
SPDT SWITCH, DC - 8 GHz
v03.1105
General Description
Features
Functional Diagram
The HMC232C8 is a broadband high isolation non-
re ective GaAs MESFET SPDT switch in a non-
hermetic surface mount ceramic package. Covering
DC to 8 GHz, the switch features >55 dB isolation
up to 2 GHz and >42 dB isolation up to 8 GHz. The
switch operates using complementary negative
control voltage logic lines of -5/0V and requires no
bias supply. This product is a form, t & functional
replacement for the HMC132C8.
Isolation: 55 dB @ 2 GHz
43 dB @ 6 GHz
Insertion Loss: 1.6 dB Typical @ 6 GHz
Non-Re ective Design
Surface Mount Ceramic Package
Direct Replacement for HMC132C8
Electrical Speci cations, TA = +25° C, With 0/-5V Control, 50 Ohm System
Typical Applications
The HMC232C8 is ideal for:
• Telecom Infrastructure
• Microwave Radio & VSAT
• Military Radios, Radar & ECM
• Test Instrumentation

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 eval-
uation circuit board shown above is available from
Hittite Microwave Corporation upon request.
