Quick and accurate design of RF base station filters

Prism Microwave uses AWR's Microwave Office circuit design software for its cavity filter tuning and optimization, as well as the design of active RF electronics and planar components on printed circuit boards, including low noise amplifiers, drivers, power amplifiers, dividers, hybrids, attenuators, oscillators, and planar/discrete filters.

The design challenge - Prism designs base station RF filters, specifically lightweight solution filters, fixed, site-tuned, and remote-tuned multi-radio combiners, as well as small cell filter solutions and lightweight mast head amplifiers. The company has stringent requirements for its RF/microwave design tools because of its commitment to rapid ramp-ups and very short time to market demands. Consequently, Prism's R&D organization has essentially no time for design (re)spins and validations of simulations versus measurements must be met quickly and accurately.
The AWR solution - AWR's Microwave Office is intuitive to use and enables Prism to achieve good circuit simulation accuracy and optimization, as well as good EM simulation for planar structures. Microwave Office also makes it possible for Prism designers to export planar structures in DXF format for layout compatibility with Mentor Graphics’ PADS tool.
Why choose AWR? Prism chose AWR’s Microwave Office for its ease of use, productivity, availability of models, and easy integration with 3rd party tools, as well as excellent customer support. For Prism designers, the most positive feature in Microwave Office is its simulation accuracy across different models. The software’s reliability and high accuracy means fewer design spins for Prism’s design teams as well as simulations that agree well with measurements.

Mika Kuokkanen, Senior RF Engineer, Prism Microwave, commented: “Microwave Office is intuitive to use. Its high quality simulation models enable us to achieve fast, accurate and optimized designs. AWR tools help us to achieve ‘Smaller, Lighter and Smarter’ products.”
