- Copal Electronics, founded in 1967 and a subsidiary of Nidec Corporation, is a global supplier to the telecommunications, computer, industrial, medical, and semiconductor equipment markets. Products designed and manufactured for these markets include trimmer and precision potentiometers, switches, optical encoders, and DC fans. Copal has also expanded its’ new product development activity into areas including silicon pressure sensors, polygon laser scanners, DC turbo fans, and thermal variable attenuators. As part of Copal’s strategy to provide the market with one of the largest portfolios of industrial switch products from one supplier, Copal Electronics completed the acquisition of the Fujisoku Corporation in late 2007. This acquisition added panel mounted toggle, rocker, lever, pushbutton, and trigger switches to an extensive range of board level switch products already manufactured by Copal. Switch product development is a focus of the combined product group in meeting market requirements for standard and customized switching solutions. Copal Electronics maintains global customer support capabilities through regional product and customer service offices located in Germany, China, Japan, Singapore, Korea, and the USA. Multiple product manufacturing facilities are located in Japan, China, and Vietnam.

- Peregrine Semiconductor, a Murata company, is a leading fabless provider of high-performance, radio frequency integrated circuits, or RFICs. The company’s solutions leverage UltraCMOS® technology, a patented, advanced form of silicon on insulator (SOI) that enables the design, manufacture, and integration of multiple RF, analog, and digital functions onto a single chip. Advancing the performance of RF SOI since 1988, Peregrine delivers the monolithic integration and superior performance necessary to solve the RF market’s biggest challenges. Peregrine holds more than 240 filed and pending patents and has shipped more than 3.5 billion UltraCMOS units. UltraCMOS technology combines the ability to achieve the high levels of performance of traditional specialty processes with the fundamental benefits of standard CMOS, the most widely used semiconductor process technology. Utilizing UltraCMOS 10 technology, Peregrine delivered the first power amplifier (PA) to meet the performance of gallium arsenide (GaAs) as a component of their Global 1 fully integrated and reconfigurable RF front-end for the mobile device market. Recent product introductions have included state-of-the-art advancements in power limiter devices, a true DC switch delivering performance down to 0 Hz and a high linearity switch that enables a dual upstream and downstream band architecture in cable premises equipment (CPE) devices—allowing CPEs to meet the stringent new requirements of the DOCSIS 3.1 cable industry standard. Peregrine’s superior linearity, power handling and harmonic performance delivers products that meet the exacting requirements in a broad range of applications in aerospace and defense, broadband, industrial, mobile wireless device, test-and-measurement (T&M) equipment, and wireless-infrastructure markets. Peregrine’s products are sold worldwide through direct sales and field applications engineering staff, and a network of independent sales representatives and distribution partners.
