New Low PIM Couplers and Dividers Bird Technologies is proud to introduce a new line of Directional Couplers and Power Dividers that have been designed to operate in demanding environments requiring exceptional passive inter-modulation (PIM) performance. All of the models have a PIM rating of -153 dBc mak- ing them suitable for many wireless applications including cellular, and land mobile radio systems. This line of low PIM components can be used to help distribute signals efficiently throughout venues without creating intermodulation products. Additionally, these units have been optimized to balance their superior performance into a very small form factor, the smallest measuring less than 3" x 2.5" x 1" (73 x 65 x 23 mm). Despite their small form factor they can handle high RF power levels while minimizing interference. Their power handling capability of up to 200 Watts covers most typical applications. All products operate over a broad fre- quency range of 698 MHz to 2.7 GHz that covers a wide variety of your ap- plications with just a few models. Couplers: The DC Series of Low PIM Couplers can be used to balance signals evenly across a coaxial DAS network. Dividers: The DD Series of Low PIM Dividers includes 2-, 3-, and 4-way versions that provide equal splitting or combining of signals with minimal losses over the splitting loss. This new family of components provides all of the high performance and high reliability you have come to expect from Bird. Visit www.tessco.com/go/bird.

Better Networks, Better Performance For Low PIM, 10 Watt Loads Since 1961, MECA has designed and manufactured an extensive line of RF/microwave components with industry-leading performance including fixed attenu- ators, directional and hybrid couplers, circulators and isolators, power divider/combiners, RF loads, integrated assemblies, DC blocks, bias tees, adapters and jump- ers, and DAS equipment. MECA serves all areas of the RF and microwave in- dustries, including world class network providers and supporting supply chain infrastructure, and has long been the backbone of high-performance wired and air-interfaced networks, such as in-building applications, satellite communications, radar, radio communications, telemetry applications, mobile radio, aviation, and air traffic communications. Our new line of 10-watt terminations features in- dustry-leading PIM performance of -175 dBc Typical to <-160 dBc (2 x 5 watt tones in cell and PCS bands), -165dBc Typcial to <-155dBc (2x20 watt tones in cell and PCS bands, additional heat sink required), while handling full rated power to +85C. All termi- nations cover frequencies of 380 MHz to 2.700 GHz, VSWR=1.10:1 Typ/1.20:1 Max. (0.698-2.700GHz) & VSWR=1.15:1 Typ/1.25:1 Max. (0.380-0.698 GHz) with 7/16 DIN, Type N, and 4.1/9.5 connectors. The line is made in the U.S. with a 36-month warranty. Visit www.tessco.com/go/meca. TESSCO No. 506987 0.380 - 2.700 GHz, 10W Low PIM Load, N Male Connector List: $307.00 Low PIM Load, N Male Connector Directional Coupler Overcoming New Challenges for Testing Distributed Cell Sites A distributed cell site architecture provides the benefit of replacing coax-based feeders with fiber-based feeders. This significantly reduces signal loss and reflections. However, since all RF functions reside on the RRH, any RF maintenance or troubleshooting such as interference analysis requires reaching the top of the tower to get access to the RRH. This represents a higher operational expense as well as safety and security concerns. These new test challenges for distributed cell sites add to existing testing requirements since the radio access network is a mix of conventional and distributed cell sites. An effective test solution must consolidate installation and maintenance tests: Cell site installation requires verification tests for coax-based feeders related to signal reflection, including return loss or voltage standing wave ratios (VSWR), distance to fault, and RF transmitted power; and, for fiber-based feeders, optical and fiber metrics including optical transmitted power and fiber inspection tests. Cell site maintenance, in addition to requiring the same verification tests performed during instal- lation, needs conformance tests related to signal integrity including RF characteristics, interference analysis, and modulation quality to ensure quality of service. Viavi's CellAdvisor TM Solution portfolio offers a comprehensive solution for the installation and maintenance of cell sites. It contains all the features and capabilities required to perform field testing of cell sites of all wireless technologies from 2G to 4G. CellAdvisor offers a simple, easy to use interface with a rich set of analytical capabilities to ensure cell-site installation, maintenance, and optimization are done correctly-and efficiently, the first time, every time. From validating coax fronthaul, fiber inspection, signal analysis, interference hunting and spectrum clearance to analyzing interference in fiber links, CellAdvisor does it all. And, it is part of a truly efficient workflow when leveraging the StrataSync cloud-based service of asset, configuration, and test-data management. Visit www.tessco.com/go/viavi solutions.
