HMC234C8
GaAs MMIC SMT HIGH ISOLATION
SPDT SWITCH, DC - 8.0 GHz
Features
Isolation: 52 dB @ 2.0 GHz
40 dB @ 6.0 GHz
Insertion Loss: 1.6 dB Typical @ 6.0 GHz
Non-Refl ective Design
Surface Mount Ceramic Package
General Description
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.
