Features High output power amplifier +23dBm P1dB at 3.3V +25dBm Psat at 3.3V Integrated Power Detector Integrated control for output power and DC current Single supply voltage: 2.7 to 3.6 V Pin compatible with SiGe Semiconductor’s SE2522L Exceptional temperature stability <1dB output power variation from –40 to +85°C Small outline plastic package For cordless telephone applications, the SE2522BL delivers up to +25dBm saturated output power at 3.3V. The SE2522BL includes a linear analog control (0.1 to 1.6V) for minimizing DC current consumption and maximizing PAE. The SE2522BL contains a digital enable for device on/off control, ramping is typical 1 µsec. The SE2522BL contains an integrated power detector with an input power range of 15dB, and an accuracy of ± 1.0dB. An accurate automatic level control function can easily be implemented using this detector circuit.
