DATA SHEET SE2425U : 2.4 GHz Bluetooth Power Amplifier IC Applications Product Description tm Bluetooth wireless technology (Class 1) A monolithic, high-efficiency, silicon-germanium power USB dongles, PCMCIA, flash cards, Access Points amplifier IC, the SE2425U is designed for 2.4 GHz TM Enhanced data rate wireless applications, including Bluetooth Class 1 basic rate and enhanced data rate applications. It Features delivers +25 dBm output power in standard rate GFSK mode and +19.5 dBm output power in enhanced rate Integrated input and inter-stage match 8DPSK. +25 dBm GFSK Output Power The SE2425U provides a digital mode control input for +19.5 dBm 8DPSK Output Power boosting the linear performance for enhanced data rate Low current: 110 mA typical P = +20 dBm OUT applications. Ultra low quiescent current: 28 mA Digital Enable for direct interface to standard The SE2425U operates at 3.3 V DC with a peak CMOS processors efficiency of 43 % in basic rate and 21 % in enhanced Mode-control for easy switching between standard rate mode. The internal bias management allows the and EDR modes part to only draw 28 mA in Class 2 output power levels. Lead Free and RoHS Compliant Output match integrates the high Q inductors to reduce Ultra thin package: 0.5 mm component count and bill of materials. It uses two 3.3 V single supply operation external capacitors to allow for varying loads, such as switches and filters, in different applications. Ordering Information The silicon/silicon-germanium structure of the SE2425U, and its exposed die-pad package, soldered Type Package Remark to the system PCB, provide high thermal conductivity and a subsequently low junction temperature. This SE2425U 3 x 3 x 0.5 mm QFN Sample device is capable of operating at a duty cycle of 100 percent. SE2425U-R 3 x 3 x 0.5 mm QFN Tape & Reel SE2425U-EK1 N/A Evaluation Kit Skyworks Solutions, Inc.
