NXP Semiconductors releases 2x2 MIMO mobile WiMAX transceivers

Continuing to deliver the technology behind the mobile lifestyle, NXP Semiconductors, the independent semiconductor company founded by Philips, announced the availability of its complete WiMAX 2x2 MIMO (Multiple Input Multiple Output)-powered family of transceivers for mobile and handheld applications.

In support of the mass deployment of mobile WiMAX, NXP’s new family of transceivers employ 2x2 MIMO technology, allowing for twice the data throughput and double the maximum speed of the company’s existing WiMAX transceiver solutions. NXP’s transceiver solutions will allow WiMAX infrastructure OEMs and ODMs to implement more robust WiMAX functionality, while achieving unparalleled savings in overall power, board real-estate and system costs.

“Imagine being able to watch interactive TV combined with graphic rich gaming on the move, or even having a multi-person video chat while accessing the internet or reading email. WiMAX is a key enabler in this vibrant portable media environment,” said Marcel van Roosmalen, general manager RF WiMAX product line, NXP Semiconductors. “Through its design innovation and strong partnerships in the WiMAX ecosystem, NXP is delivering on the promise of mobile WiMAX to offer users low cost access to broadband communication anytime, anywhere.”

One of few 2x2 MIMO WiMAX solutions in the industry, NXP’s new family of UXA234xx WiMAX transceivers improves reach and drives greater bandwidth and spectral efficiency, being particularly effective for accessing a WiMAX connection in dense urban areas. Further, because 2x2 MIMO allows for dual input and output channels, it addresses the requirements of bandwidth-intensive mobile applications, such as streaming data, voice and video data, without compromising network load and at a much lower cost to carriers. End users can thus experience speeds of up to 15 MB – three to five times faster than today's wireless broadband cellular networks.

“WiMAX is changing the way and speed that consumers will access content by permitting a quadruple play of voice, video and data transfer while on-the-move, allowing the connected consumer to engage in a truly nomadic way of life” said Will Strauss, analyst, Forward Concepts. “MIMO-powered WiMAX is significant because it delivers higher bandwidth at less cost.”

In addition, building on the success of NXP’s first family of WiMAX transceivers, the new family guarantees seamless handover from base station to base station – one of the biggest challenges facing designers of WiMAX equipment. The new family also delivers optimum interoperability with a variety of basebands by utilizing standard analog I/Q and serial interfacing, and co-exists with cellular, WLAN and Bluetooth standards.

The UXA234XX WiMAX transceivers offer a fully integrated direct-up transmitter and ZIF architecture with a small foot print of 6x6x0.85mm. The solution set supports channel bandwidths from 3.5 MHz - 20 MHz and various flexible calibration techniques for optimum performance and lowest power consumption. With no need for an external IF filter, the solution set requires minimum external components.
