LONDON NXP Semiconductors has started sampling a range of extended data rate transceivers for mobile WiMAX applications. Volume production of the devices is scheduled to start in the second quarter of the year.
The transceivers use 2x2 MIMO technology, allowing for twice the data throughput and double the maximum speed of the companyís existing WiMAX transceivers.
NXP (Eindhoven, the Netherlands), formerly Philips' semiconductor division, says the devices are one of the first on the market to deploy a MIMO architecture that allows for dual input and output channels for WiMAX.
It adds the UXA234xx WiMAX transceivers improve reach and drive greater bandwidth and spectral efficiency, being particularly effective for accessing a WiMAX connection in dense urban areas.
NXP's second generation of transceivers aimed at the growing and potentially huge WiMAX business is said to guarantee seamless handover from base station to base station Ė one of the biggest challenges facing designers of WiMAX equipment.
The devices will work with a variety of basebands by utilizing standard analog I/Q and serial interfacing, and co-exists with cellular, WLAN and Bluetooth standards. Featuring ultra-low noise, high dynamic range and high linearity, the UXA234xx transceivers allow seamless handover between base stations.
The transceivers offer a fully integrated direct-up transmitter and ZIF architecture with a small foot print of 6x6x0.85mm. They support channel bandwidths from 3.5 MHz to 20 MHz and various flexible calibration techniques for optimum performance and low power consumption.
