"SiGe provided a reference design for the power amplifier and radio ICs that made it easy to bring our design from concept to manufacture in just a few months".
SiGe Semiconductor's PA2423L evaluation board and reference design provides designers with a complete model for designing complex RF front ends.
The design, which incorporates SiGe's PA2423L and a fully equipped transceiver, is supported with documentation and in-house applications design engineers.
The PA2423L is part of SiGe Semiconductor's RangeCharger product line, which includes the PA2423x RF power amplifiers for use in cordless telephone and Bluetooth applications, as well as the SE252x devices for IEEE802.11b, 802.11a and 802.11g wireless enterprise network access.
Based on an efficient silicon germanium architecture, RangeCharger power amplifiers improve performance, range and power consumption.
The technology is proven in a variety of consumer devices on the market today from companies including Bluewinc, Brain Boxes, CSR, Samsung Electro-Mechanics, Tecom, Uniwill and W-Link.
SiGe will continue to work with these companies and others to ensure high-performance wireless access in next-generation products, supporting higher data rate operation in both the 2.4 and 5GHz frequency bands.
