Infineon Technologies AG and Global Locate Inc. have announced the development of the industry's smallest GPS receiver chip for mobile telephones, smart phones and personal navigation devices.

Based on the successful Hammerhead chip, the Hammerhead II chip is optimised for cellular handsets and mobile devices requiring high performance, low power and an extremely small footprint. The diminutive single-die chip measures only 3.74-by-3.59-by-0.6mm, for a total footprint of less than 14mm², resulting in the smallest GPS receiver.

The Hammerhead II GPS receiver includes LNA, RF down-converter and signal processing base band technology on a single RFCMOS die. The device utilises state-of-the-art chip scale packaging technology, resulting in the most compact dimensions. The package features a 49-contact Ball Grid Array, further simplifying layout and assembly.

"The Hammerhead II chip is the logical extension of our technical cooperation and outstanding partnership," added Donald Fuchs, executive vice president of Business Development for Global Locate.

Like its predecessor, the Hammerhead II chip embodies industry-leading performance, delivering sensitivity to -160dBm and position fix times as fast as 1sec, exceeding 3GPP specifications. In addition, the software has been optimised for personal navigation performance, and includes sophisticated algorithms to mitigate multipath errors.

Hammerhead II retains the same core advantages as all previous Global Locate solutions by utilising the commercially proven host-based architecture. The software is completely backward-compatible with Hammerhead, allowing an easy transition to the new, smaller part as changing form-factors require.

The Hammerhead II chip is sampling now, with production quantities available in February 2007. Infineon and Global Locate are jointly marketing the chip.
