General Description

Features

Functional Diagram

High Isolation: 43 dB @ 2 GHz

Low Insertion Loss: 0.7 dB @ 2 GHz

Single Positive Supply: Vdd = +5V

Integrated 2:4 TTL Decoder

3x3 mm SMT Package

Typical Applications

The HMC241LP3 / HMC241LP3E is ideal for:

• Base Stations & Repeaters

• WLAN, WiMAX & WiBro

• CATV / DBS

• Test Equipment

The HMC241LP3 & HMC241LP3E are general pur-

pose non-reflective SP4T switches in low cost lead-

less surface mount packages. Covering DC - 4 GHz,

this switch offers high isolation and has a low insertion

loss of 0.7 dB at 2 GHz. The switch offers a single

positive bias and true TTL/CMOS compatibility. A

2:4 decoder is integrated on the switch requiring

only 2 control lines and a positive bias to select each

path, replacing 4 to 8 control lines normally required

by GaAs SP4T switches.
