Product Description
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.
