The following ZIP file contains S-Parameters in a Libra format for our ERA series of monolithic amplifiers. This data is provided in the hope that you will benefit from its use. We have endeavored to provide you with the best data we can but believe there is some amount of the test fixture still in the data. We hope to improve the data in the future but wanted you to have what is available now. Please let me know if you need help finding PKWARE software, unzipping the data with PKWARE software, have problems with the data or need other assistance. Regards, Doug Hopper DH@minicircuits.com
