The Keysight Technologies, Inc. L4490A/91A RF switch platform simplifies the task of defining and build-

ing a custom switch matrix. Engineers are often under pressure to lower cost and get to market quickly. The

L4490A/91A provides the right tools to easily define and build a custom switch matrix while reducing your

overall design time – all without sacrificing signal integrity. In addition, with the robust design, you can have

confidence in the reliability and longevity of your system.

The RF switch platform easily integrates into your test environment with standard rack mount kits, LAN

and GPIB connectivity, graphical web interface and software drivers for the most common programming

environments.

This platform is ideal for R&D and manufacturing engineers creating custom switch matrices for A/D and

wireless applications testing mobile radios, handsets, basestations, radio components, and other wireless

devices. Also, with the broad range of supported switches up to 50 GHz, you can future-proof your invest-

ment for emerging standards like WiMAXTM, LTE and UMB.

Build custom designs from multiplexers, blocking or non-blocking matrices or a combination of both with

signal conditioning to meet your unique needs.
