Broadcom is addressing the daunting challenge of keeping mobile wireless handsets small and consuming little power, while adding new functions, with a new chip that combines Wi-Fi, Bluetooth, and FM, or frequency modulation.
Broadcom reported Friday that its 65-nanometer CMOS system-on-a-chip solves the difficult problem of self-interference among different devices operating in the same frequency band.
The BCM4325 uses Broadcom's InConcert algorithms to solve interference problems between Wi-Fi and Bluetooth, which both operate in the 2.4-GHz frequency range. "Until now," the firm said, "integrating these technologies in a single product was challenging since multiple radios in the same band can lead to self-interference."
Broadcom noted that FM radio is gaining momentum in handset design with the result that entertainment and news telecasts are rapidly becoming important applications.
The single chip features IEEE 802.11a/b/g integration and supports Bluetooth 2.0.
