HMC199MS8

DUAL SPDT SWITCH

DC - 2.5 GHz

v03.0404

General Description

Features

Functional Diagram

Integrated Dual SPDTs

Low Insertion Loss: <0.5 dB @ 2.0 GHz

Positive Control: 0/+5V

Typical Applications

The HMC199MS8 is ideal for:

• Cellular

• ISM Basestations

• PCS

The HMC199MS8 is a low-cost dual SPDT GaAs

“bypass” switch in an 8-lead MSOP package cover-

ing DC to 2.5 GHz. This four RF port component

integrates two SPDT switches and a through line

onto a single IC. The design provides low insertion

loss of less than 0.5 dB while switching passive or

active external circuit components in and out of the

signal path. Port to port isolations are typically 25

to 30 dB. On-chip circuitry enables positive voltage

control operation at very low DC currents with con-

trol inputs compatible with CMOS and most TTL

logic families.

Applications include LNA or filter

bypass switching and single bit attenuator switch-

ing.
