Radio front-ends for mobile handsets are a critical analog signal processing function, implemented today with fixed frequency, narrow band filter elements and switches. This architecture results in costly custom designs for every operator or region, leading to increases in size, cost and power consumption, with each new generation of handset, as more frequency bands are required. By focusing on frequency agile architectures and components, Newlans has developed a front-end module (FEM) solution which delivers tremendous size, costs, and power benefits over traditional RF architectures. Multiple duplexers and switches are replaced by a single, Programmable Duplexer™ that covers the entire 3G and 4G / LTE frequency range, allowing a single FEM design to support multiple operators and regions by simply programming it for the appropriate bands.
Operators around the world are seeking to expand their coverage by using local, inexpensive base stations collectively referred to as small cells. These nodes are being designed and deployed to cover varying size areas both indoors and out, must also protect their spectrum from interference from competing sources. Newlans programmable RF technology enables the development of a single equipment model which operates across locations and regions for either single-mode or multi-mode operation. The programmability of Newlans solutions enables operators to filter out interference from region specific blockers, allowing them to benefit from greater capacity utilization, simplified deployment planning, and lower inventory costs.
