GaAs MMIC SOT26 SPDT

SWITCH, DC - 3 GHz

General Description

Features

Functional Diagram

RoHS-Compliant Product

Low Insertion Loss: 0.4 dB

Ultra Small Package: SOT26

Input IP3: +45 dBm

Positive Control: 0/+3V @ 10 uA

Included in the HMC-DK005 Designer’s Kits

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 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.
