Infineon And Global Locate Develop The Smallest GPS Receiver
Infineon Technologies and Global Locate announced the successful development of the industry’s smallest Global Positioning System (GPS) receiver chip for mobile telephones, smart phones and personal navigation devices.
Based on the Hammerhead chip, the new Hammerhead II chip is optimized 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 mm x 3.59 mm x 0.6 mm, for a total footprint of less than 14 mm², resulting in the world’s smallest GPS receiver.
The Hammerhead II GPS receiver includes LNA, RF down-converter and signal processing baseband technology on a single RFCMOS die. The package features a 49-contact Ball Grid Array, further simplifying layout and assembly.
The Hammerhead II chip delivers sensitivity of -160 dBm and position fix times of as fast as 1 second, exceeding 3GPP specifications. In addition, the software has been optimized 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 utilizing 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.
