General Description
8
The HMC197 & HMC197E are low-cost SPDT switches
in 6-lead SOT26 plastic packages for use in general
switching applications which require very low inser-
tion 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 applica-
tions with less than 1 dB loss. The design provides
exceptional insertion loss performance, 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 families. See HMC221
for same performance in an alternate SOT26 pin-out.
