Dr. Richard Snyder of RS Microwave

This talk presents advanced structures that extend the class of capacitivelyloaded evanescent mode filters and mitigate some of the limits that are common for this technology. Innovative design details and modifications with respect to a conventional structure are properly applied so as to improve the filter performance when high power, broad passband, and wide stopband are all required at relatively high frequency. The proposed structures combine coaxial capacitance based resonators with evanescent mode ridged waveguide sections so as to obtain capacitively-loaded ridge waveguide bandpass filters. The approach is validated by the design and experimental results of two X- and Ku-band filters. Particularly remarkable are the performance of the Ku-band filter, which has a wide passband from 12 to 18 GHz, a wide stopband up to 54 GHz, and which successfully handled 100 W of continuous power.

Biography: Richard V. Snyder is President of RS Microwave (Butler, NJ, USA), author of 94
papers, three book chapters and holds 19 patents. His interests include E-M
simulation, network synthesis, dielectric and suspended resonators, high power
notch and bandpass filters and active filters. He received his BS, MS and PhD
degrees from Loyola-Marymount, USC and Polytechnic Institute of New York. Dr.
Snyder served the IEEE North Jersey Section as Chairman and 14 year Chair of the
MTT-AP chapter. He chaired the IEEE North Jersey EDS and CAS chapters for 10
years. He twice received the Region 1 award. In January 1997 he was named a
Fellow of the IEEE and is now a Life Fellow. In January 2000, he received the IEEE
Millennium Medal. Dr. Snyder served as General Chairman for IMS2003, in
Philadelphia. He was elected to ADCOM in 2004. Within the ADCOM, he served as
Chair of the TCC and Liaison to the EuMA. He served as an MTT-S Distinguished
Lecturer, from 2007-2010, as well as continuing as a member of the Speakers
Bureau. He was an Associate Editor for the IEEE Transactions on Microwave
Theory and Techniques, responsible for most of the filter papers submitted. He is a
member of the American Physical Society, the AAAS and the New York Academy of
Science. He was the MTT-S President for 2011. Also a reviewer for IEEE-MTT
publications and the MWJ, Dr. Snyder teaches and advises at the New Jersey
Institute of Technology He is a Visiting Professor at the University of Leeds, in the
U.K. He served 7 years as Chair of MTT-8 and continues in MTT-8/TPC work. He is
the organizer of the annual IWS conference in China. He previously was Chief
Engineer for Premier Microwave.
