It typically provides +20dBm linear output power requiring only 110mA at 3.3V. It can also be utilized in 2.4GHz cordless telephone applications where it typically provides +23dBm saturated output power at 3.6V. The SE2522 includes an integrated power detector circuit for closed loop monitoring of output power. It has an input power range of 15dB with an accuracy of ±1.0dB. An accurate automatic level control function can easily be implemented using this power detector circuit. The SE2522L contains a linear analog control (0.1 to 1.6V) for minimizing DC current consumption and maximizing PAE. The SE2522L includes a digital enable control for device on/off control where ramping is typically 1 µsec.
