Insertion Loss: 1.6 dB Typical @ 6 GHz
Non-Reflective Design
Surface Mount Ceramic Package
General Description
The HMC234C8 is a broadband high isolation non-
reflective GaAs MESFET SPDT switch in a non-
hermetic surface mount ceramic package. Covering
DC to 8 GHz, the switch features >52 dB isolation
up to 2 GHz and >38 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 an excellent pin-for-pin
replacement to the SMDI SSW124.
