Functional Diagram
General Description
The HMC197B(E) 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 sig-
nals from DC to 3 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
HMC221B(E) for same performance in an alternate
SOT26 pin-out.
