SPDT NON-REFLECTIVE

SWITCH, DC - 3.5 GHz

v06.0607

General Description

Features

Functional Diagram

High Isolation: >45 dB

Positive control: 0/+5V

Non-Reflective Design

Ultra Small Pakcage: MSOP8G

Indluded in the HMC-DK005 Designers’ Kit

0/+5 Vdc, 50 Ohm System

Typical Applications

The HMC284MS8G / HMC284MS8GE is ideal for:

• Cellular/PCS Base Stations

• 2.4 GHz ISM

• 3.5 GHz Wireless Local Loop

The HMC284MS8G & HMC284MS8GE are low-cost

SPDT switches in 8-lead grounded base MSOP pack-

ages. The design has been optimized to provide high

isolation with minimal insertion loss for medium and

low power applications. On-chip circuitry allows posi-

tive voltage control operation at very low DC currents

with control inputs compatible with CMOS and most

TTL logic families. In the “OFF” state, RF1 and RF2

are non-reflective. See reflective high isolation SPDT

version, HMC194MS8.
