Title:
Filtering Solutions Improve Dynamic Range of IMD, Intermodulation and Triple Beat Testing for 3G, 4G and LTE Applications

Date & Time:
September 12, 2013; 8 AM PT/ 11 AM ET/ 3 PM UTC

Presented by:
K&L Microwave Inc.

Abstract:
Traditional test setups for IMD, IP3, and triple beat testing of LTE 3G and 4G components use a combination of filters, attenuators and hybrid combiners to combine signals while keeping power inputs to spectrum analyzers to acceptable levels. The use of attenuators, specifically, reduces the dynamic range of the spectrum analyzer thereby making the tests less reliable. Reflections caused either by the device under test or mixing of signals in the test setup further degrades the systems test performance. This webinar will discuss several innovative filtering solutions to minimize, or eliminate, the use of attenuators while increasing the systems overall return loss. Together these approaches significantly increase the dynamic range of any test setup.

Presenter:
Rafi Hershtig, Vice President of Advanced Component Engineering,K&L Microwave

Biography:
In 1985, Rafi Hershtig received a bachelor’s degree in electrical engineering from the Ben-Gurion University in Beer Sheva, Israel. From 1985 to 1989 he worked for the microwave department of ELTA, focusing on the development of switched filter banks and switched multiplexers.

In 1989, Rafi joined K&L Microwave and worked on the development of filter-based subsystems. Since 1992, he has focused on the research and design of new product lines, including printed filters in S.S.S. form and dielectric resonator filters. He has been involved with K&L’s wireless application group since 1995, designing high “Q” elliptic response filters and delay line assemblies with the in-house design program CKTTOOL.

In 2001, Rafi received his M.Sc. degree in wireless communications from NTU. Much of the last decade has been dedicated to serving the military market, producing high-power, small-volume filter assemblies, surface mount filters, and multiplexers. Research in mixed technologies has yielded highpass and lowpass filters with very sharp roll-off. Support of the commercial market has included development of low-PIM filtering solutions and addressing 4G-LTE testing needs. In addition, Rafi holds 6 patents.
