Smaller footprint aids amplifier adoption

The SiGe Semiconductor RangeCharger PA2423L has been selected by Uniwill Computer Corp for its Class 1 Bluetooth products.

The SiGe Semiconductor RangeCharger PA2423L has been selected by Uniwill Computer Corp for its Class 1 Bluetooth products.

The device has been integrated into Uniwill's BTM2022-1-Y module, which is widely implemented into consumer products like the B191H1 USB dongle, B190N1 access point, and a series of notebook PCs.

Uniwill is among the growing list of equipment manufacturers to select the PA2423L for Class 1 Bluetooth products.

The PA2423L is a small form factor variant of SiGe's popular PA2423 family of RangeCharger power amplifiers, known for an extremely efficient silicon germanium architecture that enables excellent power output for enhanced range, and very low power consumption for longer battery life.

These benefits have secured SiGe's place as the leading supplier of power amplifiers for the Class 1 Bluetooth market - with about 55% of the market share in 2001 according to In-Stat/MDR.

Since the lead device launched in June 2000, more than a million RangeCharger power amplifiers have been shipped, many of which can be found in certified Bluetooth Class 1 products that are on the market today.

"I am delighted with our leadership position in the Bluetooth market, as it underscores our ability to identify opportunities, and quickly mobilise to bring solutions to market that meet OEM requirements", said Bill Cuming, vice president optical, cable and components, SiGe Semiconductor.

"Uniwill's implementation of the PA2423L adds to our track record in delivering solutions that drive higher performance and reliability into the hands of consumers".

Uniwill's Class 1 products fully exploit the benefits of SiGe's PA2423L.

The power amplifier 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.

The BTM2022-1-Y module exhibits this benefit, able to support stable 1Mbit/s throughput over line-of-site connections up to 400m.

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 portable, battery-operated equipment.

"We are pleased to be working with SiGe, since their strategy is synergistic with our roadmap to develop products that accelerate the acceptance of Bluetooth across the computing and communications markets", said Mark Tung, Communication RD Manager, Uniwill Computer Corporation.

"Their power amplifier has enhanced the performance, form factor and battery life of our products, thereby improving the user experience for next-generation mobile applications".
