Dual-Band 802.11n 2x2 PCI Express® Half MiniCard

Currently Viewing:

Single-chip baseband/MAC/radio all-in-one die with integrated dual-band power amplifiers for 2x2 2.4 GHz and 5 GHz 802.11n applications.
The low-cost CMOS implementation for MAC (Media Access Control), Baseband and Radio allows integration with Broadcom's Cable/DSL/Set-top/VoIP chipsets. The BCM43224 has the industry's first integrated dual-band 802.11n power amplifiers, eliminating the need for external power amplifiers, significantly reducing the rest-of-BOM (RBOM) and footprint. This solution is fully compatible with IEEE 802.11n Draft 2.0 and 802.11a/b/g Not Recommended for New Design devices. It has two transmitters and two receivers with optional 802.11n Draft 2.0 modes to allow data rates supporting up to 300 Mb/s. Broadcom's Intensi-fi® XLR increases rate vs. range of existing 802.11n networks. The increased rate and range provides user satisfaction and reduces product support call volume. This single-chip 65 nm solution with integrated dual-band power amplifiers drives down the cost of 802.11n solutions into the consumer and media space. The highly integrated CMOS (Complimentary Metal-oxide Semiconductor) and low-power modes result in a 50 percent power reduction compared to previous generation solutions.
