Figure 3_7_1. WiFi Module BLOCK DIAGRAM

The Broadcom® BCM4329 family of single chip devices provide the optimum integration of IEEE 802.11™

a/b/g and 802.11n (MAC/ baseband/radio) handheld device classes, Bluetooth® 2.1 + EDR (Enhanced Data

Rate), and FM radio receiver and transmitter features in mobile and handheld wireless systems. The

BCM4329 addresses the needs of compact mobile devices that require minimal power consumption. The

BCM4329's integrated 2.4 GHz and 5 GHz WLAN CMOS power amplifiers offer the lowest cost dual-band

solution in the industry. The BCM4329 utilizes advanced design techniques and process technologies to

reduce active and idle power consumption and extend battery life, while maintaining robust connectivity

and providing a rich set of features. The BCM4329's highly sophisticated InConcert radio coexistence

algorithms and hardware mechanisms allow for an extremely collaborative coexistence scheme and

provide coexistence support for a single shared antenna and external radios (including WiMax™ and

cellular radio technologies). As a result, the BCM4329 enhances the overall quality of simultaneous voice,

video, and data transmission of handheld systems, while minimizing the footprint. The BCM4329's

integrated power management unit simplifies the power topology, enabling operation directly from the

mobile's platform battery. Along with the integrated power amplifiers, the BCM4329 includes integrated

transmit and receive baluns to further reduce overall cost.
