Keysight ADS Libraries

Reduce your design cycle time with our extensive set of design libraries - completely free!

Complete design libraries available for Keysight ADS, AWR, and Eagleware.
S-parameter data provided for many of our components.
MLC/MLI software outputs s2p files for easy import into your EM simulator.
Now offering scalable board substrate thickness and dielectric constant modeling for capacitors and inductors, in collaboration with Modelithics Inc.

New!

Keysight ADS PathWave EM Design (EMPro) Encrypted Chip Antenna Models

By using these new libraries, design engineers can quickly simulate different antenna configurations, environments, and optimize their designs for factors such as gain, bandwidth, radiation pattern, and impedance matching.

Ideal for IoT and RF wireless communication systems.

Keysight ADS Libraries

Johanson ADS Libraries are the latest Software Tools designed to give users of Keysight's Advanced Design System simulation software (Ver 1.5 and up) easy access to Johanson Capacitor and Inductor data (S-parameter based ) (and now the Newly Available Band Pass Filters, Low Pass Filter, Antennas, Baluns and Couplers libraries) during simulation runs. Both schematic and layout formats are supported.

If you are familiar with Johanson Libraries and have the files listed below, select an ADS Library on the right. If you are a first time user, please see the help file below.
