General Description
The HMC239S8 is a low-cost GaAs MMIC SPDT
switch in an 8-lead SOIC package. The switch
can control signals from DC to 2.5 GHz. It is
especially suited for low or medium power appli-
cations which require extremely fast switching
with minimal insertion loss. The two control volt-
ages require a minimal amount of DC current
which is optimal for battery powered radio sys-
tems. RF1 and RF2 are reflective shorts when
“Off”.
