CTS Electronic Components Inc. introduces the ClearPlexTM Waveguide Ceramic Filter, a revolutionary RF ceramic filter that offers space and cost saving features, as well as superior performance, compared to air-cavity filters in small-cell applications.

Air-cavity filters have been the prime choice for macro-cells topology for their superior overall performance and power handling. However, air-cavity filters are large, heavy, and expensive which are not ideally suited for small-cell applications. Design engineers must find a solution that can maintain a high level of performance while offering other critical benefits such as space and cost savings. CTS’ ClearPlexTM Waveguide Ceramic Filters offer that solution.

ClearPlex™ waveguide technology takes advantage of CTS‘ patented mechanical structures and proprietary high quality ceramic formulations. It offers a solution that satisfies the market’s needs for low cost, small size, and superior electrical performance. Key attributes offered by ClearPlex™ filter include low insertion loss of less than 2.5 dB, sharp rejection points reaching up to -80 dB, and Passive Intermodulation (PIM) levels averaging -110 dBm.

The initial band pass filter (BPF) availability will be offered for UMTS bands 1, 2, 4, 7, and 25. These could be used in time-division duplexing (TDD) or frequency-division duplexing (FDD) mode with onboard coupling. Expansion to other band and variations may be available upon request.

The ClearPlexTM Waveguide Ceramic Filter will be showcased at the IEEE MTT-S International Microwave Symposium 2013 in Seattle, Washington USA on June 4-6 at booth number 918. For more information on the ClearPlexTM Waveguide Ceramic Filter and other ceramic filters, please contact your local CTS Sales Representative or supporting CTS Inside Sales Representative or visit http://www.ctscorp.com/components or ceramicsales@sales.com
