Prism Microwave Maximizes R&D Efficiency for Base Station Filter Design


Company Profile

Prism Microwave is a technology leader in RF filtering. Its exceptional RF-filter know-how is a capability that’s utilized by OEMs, mobile operators, and consumers (via distributors) for developing and marketing business-to-business (B2B) RF-filtering solutions. 

Additionally, Prism’s product portfolio provides its customers with repair and refurbishment services, as well as technology consulting for specific RF challenges. Prism Microwave has locations in Dallas, Texas and Oulu, Finland with production facilities in Suzhou, China.

The Design Challenge

Prism designs base station RF filters, specifically lightweight solution (LWS) filters, fixed, site-tuned, and remote-tuned multi-radio combiners (MRCs), 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® circuit design software is used for Prism’s cavity filter tuning and optimization. It is also used to design Prism’s active RF electronics and planar components on printed circuit boards (PCBs), including low-noise amplifiers (LNAs), drivers, power amplifiers (PAs), dividers, hybrids, attenuators, oscillators, and planar/discrete filters. 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 Did You 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.
