SE2425U 2.4 GHz Bluetooth Power Amplifier IC
A monolithic, high-efficiency, silicon-germanium power amplifier IC, the SE2425U is designed for 2.4 GHz wireless applications, including BluetoothTM Class 1 basic rate and enhanced data rate applications. It delivers +25 dBm output power in standard rate GFSK mode and +19.5 dBm output power in enhanced rate 8DPSK. The SE2425U provides a digital mode control input for boosting the linear performance for enhanced data rate applications. The SE2425U operates at 3.3 V DC with a peak efficiency of 43 % in basic rate and 21 % in enhanced rate mode. The internal bias management allows the part to only draw 28 mA in Class 2 output power levels. Output match integrates the high Q inductors to reduce component count and bill of materials. It uses two external capacitors to allow for varying loads, such as switches and filters, in different applications. The silicon/silicon-germanium structure of the SE2425U, and its exposed die-pad package, soldered to the system PCB, provide high thermal conductivity and a subsequently low junction temperature. This device is capable of operating at a duty cycle of 100 percent.
