WLAN 802.11b/g and BT V2.0 EDR Module

SyChip Inc. introduces the types HU and XX, WLBT8120 / WLBT8121, a dual radio module conforming to IEEE 802.11b/g wireless LAN and Bluetooth version 2.0 with Enhanced Data Rate.

The new Module provides the best of both wireless LAN and Bluetooth in a compact package. The feature set for WLAN includes IEEE 802.11i security, Quality of Service (QoS) traffic prioritization for VoIP and multimedia applications, an ultra low power sleep mode. The feature set for Bluetooth includes v2.0 with EDR for high throughput along with real time data profiles for audio packets. An internal Bluetooth signaling interface along with AFH is utilized for enhanced co-existence for the two radios who share the same 2.4 GHz spectrum.

The modules provide two RF interfaces to support independent antenna configurations. The primary benefit of dual antenna is maximized range and best coexistence flexibility.

This module is targeted to Mobile Phones and consumer electronics where high integration, proven coexistence, and fast design cycles are highly valued.

The module integrates the latest silicon technology for mobile client Wireless LAN and Bluetooth offering the best feature set while minimizing space and power consumption.

This module utilizes a QFN package and allows direct attachment to the main Printed Circuit board utilizing industry standard surface mount technology processing for high volume production.
