• Manufacturer Part Number: BCM4325GKFBG
• Description: SINGLE CHIP IEEE 802.11a/b/g MAC/BASEBAND/RADIO WITH INTEGRATED BLUETOOTH 2.1 + EDR AND FM RECEIVER FOR LOW-POWER MOBILE HANDSET
• Manufacturer: BOARDCOM [Broadcom Corporation.]

The Broadcom BCM4325 family of single-chip devices provides for the
highest level of integration for a mobile or handheld wireless system,
with integrated IEEE 802.11a/b/g (MAC/Baseband/Radio), Bluetooth
2.1 + enhanced data rate (EDR), and FM receiver. Thus providing a
compact small form factor solution with minimal external components to
drive the costs for mass volumes and allows for flexibility in size, form,
and function of handheld devices. The BCM4325 is designed to address
the needs of highly mobile devices that require minimal power
consumption and reliable operation.
The BCM4325 utilizes advanced design techniques and process
technology to deliver the lowest active and idle power, extending the
system battery life while maintaining consistent connectivity, and still
provides a rich set of features.
The BCM4325 implements the highly sophisticated InConcert radio
coexistence algorithms and hardware mechanisms allowing for an
extremely collaborative coexistence scheme along with coexistence
support for external radios (such as GPS, WiMax, or Ultra Wide-Band
radio technologies, as well as cellular radios) and a single shared
Antenna. As a result, it enhances the overall quality for simultaneous
voice, video, and data transmission on a handheld system while
minimizing the footprint.
The BCM4325 further integrates a power management unit simplifying
the power topology on a system and allowing for operation directly from
the handheld battery. It also integrates a CMOS power amplifier to meet
