General Description
The HMC221A(E) is a low-cost SPDT switch in
a 6-lead SOT26 plastic package for use in gen-
eral switching applications which require very low
insertion loss and very small size. This device
can control signals from DC to 3 GHz and is
especially suited for 900 MHz, 1.8 - 2.2 GHz, and
2.4 GHz ISM applications with less than 1 dB loss.
The design provides exceptional insertion loss perfor-
mance, ideal for filter and receiver switching. RF1 and
RF2 are reflective shorts when “Off”. The two control
voltages require a minimal amount of DC current and
offer compatibility with most CMOS & TTL logic fami-
lies. See HMC197A(E) for same performance in an
alternate SOT26 pin-out.
