SE2425U power amplifier

SiGe Semiconductor has expanded its series of RangeCharger ICs with a miniature power amplifier optimized for both standard Bluetooth and enhanced data rate (EDR) applications. The SE2425U power amplifier is based on a silicon germanium architecture that allows EDR to be supported over longer distances when implemented in Bluetooth-capable cellphones, PDAs, wireless headsets, laptops and cordless telephones.

The new power amplifier is designed to boost performance and reduce current consumption of devices compliant to both the Bluetooth v2.0 specification and EDR protocol. SiGe said the product offers benefits such as low current consumption, power saving modes and low quiescent current, which allows Class 1 and Class 2 operation to be supported in battery-powered mobile devices.

The SE2425U delivers 25dBm output power in standard rate Gaussian frequency-shift keying mode and 19.5dBm output power in enhanced rate 8DPSK. This allows systems based on the device to deliver 20dBm at the antenna in either mode.

The product is housed in a 16-pin QFN package that measures 3-by-3-by-.5mm. The complete circuit requires two external capacitors.

The SE2425U is already available, and is priced at 95 cents in quantities of 10,000.
