Functional Diagram
General Description
The HMC221 is a low-cost SPDT switch in a 6-lead
SOT26 plastic package for use in general switching
applications which require very low insertion loss
and very small size. The device can control signals
from DC to 3.0 GHz and is especially suited for
900 MHz, 1.8 - 2.2 GHz, and 2.4 GHz ISM appli-
cations with less than 1 dB loss. The design pro-
vides exceptional insertion loss performance, ideal
for filter and receiver switching. RF1 and RF2 are
reflective shorts when “Off”. The two control volt-
ages require a minimal amount of DC current and
offer compatibility with most CMOS & TTL logic
families. See HMC197 for same performance in an
alternate SOT26 pin-out.
