General Description
The HMC221 and HMC221E are low-cost SPDT
switches in a 6-lead SOT26 plastic package for
use in general switching applications which require
very low insertion loss and very small size. These
devices 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 per-
formance, ideal for filter and receiver switching. RF1
and RF2 are reflective shorts when “Off”. The two
control voltages require a minimal amount of DC cur-
rent and offer compatibility with most CMOS & TTL
logic families. See HMC197 for same performance in
an alternate SOT26 pin-out.The HMC221E is a RoHS-
compliant product.
