GaAs MMIC SOT26 SPDT

SWITCH, DC - 3 GHz

v02.0505

General Description

Features

Functional Diagram

Low Insertion Loss: 0.4 dB

Ultra Small Package: SOT26

Input IP3: +45 dBm

Positive Control: 0/+3V @ 10 uA

Typical Applications

The HMC197 / HMC197E is ideal for:

• MMDS & WirelessLAN

• PCMCIA Wireless Cards

• Portable WIreless

The HMC197 & HMC197E are low-cost SPDT

switches in 6-lead SOT26 plastic packages 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 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 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.
