General Description
Features
Functional Diagram
The HMC234C8 is a broadband high isolation
non-refl ective GaAs MESFET SPDT switch in a
non-hermetic surface mount ceramic package.
Covering DC to 8.0 GHz, the switch features >52
dB isolation up to 2 GHz and >38 dB isolation
up to 8.0 GHz. The switch operates using
complementary negative control voltage logic
lines of -5/0V and requires no bias supply. This
product is an excellent pin-for-pin replacement to
the SMDI SSW124.
Isolation: 52 dB @ 2.0 GHz
40 dB @ 6.0 GHz
Insertion Loss: 1.6 dB Typical @ 6.0 GHz

Evaluation PCB
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 avail-
able from Hittite Microwave Corporation upon request.
