Typical Applications

The HMC221 & HMC221E is ideal for:

• ISM Applications

• PCMCIA Wireless Cards

• Cellular Applications

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 3.0 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 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.
