DESCRIPTION

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. Remark Samples Shipped in Tape & Reel This device is capable of operating at a duty cycle of 100 percent.
