HMC245AQS16 / 245AQS16E

v00.1213

GaAs MMIC SP3T Non-REFLECTIVE

SWITCH, DC - 3.5 GHz

General Description

Features

Functional Diagram

The HMC245AQS16 & HMC245AQS16E are low cost

non-reflective SP3T switches in 16-lead QSOP sur-

face mount packages. Covering DC to 3.5 GHz, the

switch offers 30 to 40 dB isolation and a low inser-

tion loss of 0.7 dB.

A 2:3 TTL/CMOS compatible

decoder is integrated on the switch requiring only 2

control lines and a single +5V bias to select each path,

replacing 6 control lines normally required by GaAs

SP3T switches.

Low Insertion Loss: 0.7 dB @ 2.0 GHz
