BBP1 is a fully programmable radio baseband processor optimized for Wireless LAN applications (802.11a/b/g). It was built to demonstrate the flexibility and performance of our architecture.

A clock frequency of 160 MHz is required to run 802.11a, which is the most demanding of the implemented standards. In addition to the WLAN standards the processor can also manage less demanding standards e.g. Bluetooth and GSM/GPRS. A die photo of the manufactured chip as well as chip data and measurment results are given below.
