NXP Semiconductors has announced the availability of its complete WiMAX 2x2 multiple input multiple output (MIMO)-powered family of transceivers for mobile and handheld applications. In support of the mass deployment of mobile WiMAX, NXP’s new family of transceivers employs 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 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.

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. Furthermore, 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.

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 using 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 footprint of 6 mm x 6 mm x 0.85 mm. The solution set supports channel bandwidths from 3.5 MHz to 20 MHz and various flexible calibration techniques for optimum performance and lowest power consumption. The solution set requires minimum external components.

The UXA23466 and UXA23476 WiMAX 2x2 MIMO transceivers are sampling. Volume production will start in Q2. Sample pricing starts at around $13.50.
