UWB Reference Designs Make Wireless USB A Cinch

With a maximum data rate of 480 Mbits/s, wireless USB ports represent a key Ultra-Wideband (UWB) application. Wisair offers ready-to-go reference designs for a wireless USB hub and dongle that let manufacturers offer wireless USB products right now.

The dongle plugs into any standard USB port, making a PC, laptop, or any other device fully wireless as well as compatible with USB 2.0. The hub design accommodates up to four USB devices, such as printers, scanners, remote hard drives, and digital cameras. It can be located as far away as 30 ft from the PC.

These reference designs are based on Wisair's second-generation UWB chip set, which includes the 502 silicon-germanium RF transceiver and the 531 CMOS baseband processor. Combining the set with a USB interface chip produces a complete wireless USB product.

The set is fully WiMedia-compatible. With its detect and avoid (DAA) capability, the transceiver can listen to and search for signals and then automatically switch to other frequencies to avoid interference and coexist with other wireless systems in the same bands.
