Receiver greatly simplifies dual-antenna system design because it integrates antenna sensing, switching and a high-performance low-noise amplifier.
"Extending Bluetooth to the PC motherboard is an indication that Bluetooth is here to stay", said Bill Cuming, vice president optical, cable and components, SiGe Semiconductor.
"We are very happy to be working with MSI as a pioneer in bringing this wireless technology to the PC motherboard, and are encouraged by the new opportunities that will be enabled for wireless Internet access, gaming, file sharing and peripheral control".
The PA2423L is a small form factor variant of SiGe's widely implemented PA2423 family of RangeCharger power amplifiers.
Packaged in a 6-lead LPCC that measures only 1.6 x 3.0mm, the PA2423L is the smallest fully encapsulated Bluetooth Class 1 power amplifier on the market.
This, combined with the device's ultra-low power consumption, makes it ideal for MSI's compact PC motherboard and small form factor USB dongle.
Based on an extremely efficient silicon germanium architecture, the PA2423L also provides industry-leading performance with power output of +22.5dBm and 45% power-added efficiency.
This allows the device to overcome antenna and filter losses, thereby enhancing signal integrity and stability, even over extended transmission ranges.
MSI's PC2PC-Bluetooth kit exhibits this benefit, able to support stable performance of 1Mbit/s throughput over connections of 100m, despite physical barriers.
"Bluetooth-enabled printers, cameras, and a host of other products are available today.
However, for wide consumer acceptance, the technology must provide seamless, easy-to-use connections - requirements best met by integrating it onto the PC motherboard", said Branda Lin, product manager, MSI.
"To that end, we selected ICs that met the specification, without affecting the form factor or power consumption.
SiGe's power amplifiers fit that description, and we'll consider them as we continue to develop our PC2PC product lines for Bluetooth and WLAN applications".
