Functional Diagram
General Description
The HMC197 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 applications with less than 1
dB loss. The design provides exceptional inser-
tion loss performance, ideal for 鏗乴ter and receiver
switching. RF1 and RF2 are re鏗俥ctive shorts
when 鈥淥ff鈥? The two control voltages require a
minimal amount of DC current and offer compat-
ibility with most CMOS & TTL logic families. See
HMC221 for same performance in an alternate
SOT26 pin-out.
