Single-chip base band processor and RF transceiver

23 February 2005 Telecoms, Datacoms, Wireless, IoT

Infineon Technologies has announced its E-GOLDradio chip - a GSM/GPRS single-chip that combines a quadband radio transceiver part with a base band processor. This chip enables the base band and RF functionality to be realised within a board space of less than 4 cm² - about 30% less than the area previously occupied by two-chip solutions. Featuring E-GOLDradio, Infineon claims it is able to provide the world's most integrated platform. The new BP3 platform comprises all hardware and software components necessary to design a mobile phone, such as power management, filter, power amplifier, memory as well as a GSM/GPRS protocol stack and application framework (APOXI) with a reference man-machine interface. With this new chip Infineon overcame one of the most-challenging issues when integrating base band logic and RF parts close to each other on one single chip, such as crosstalk attenuation. The IC supports up to GPRS class 12.
