Abstract
A dual mode regulator provides power to a tower mounted low noise amplifier (LNA) and operates in either one of two modes. The dual mode regulator comprises a microcontroller that controls the amplifier and two regulators to operate in an Antenna Interface Standards Group (AISG) mode when the microcontroller is detecting AISG protocol information or in a current window alarm (CWA) mode when the microcontroller is not receiving AISG protocol information. In the CWA mode the total current to the two regulators and associated circuitry is maintained at a constant amplitude. Further in the CWA mode, the microcontroller is able to generate an alarm signal and deactivate the amplifier when it detects improper operation by the amplifier. In the AISG mode, a single regulator is used and the other regulator is de-activated by the microcontroller.
