Abstract:
In a wireless communications system including a radio frequency (RF) re-transmitter, said RF re-transmitter adapted to receive and re-transmit wireless signals, said RF re-transmitter including an output amplifier and automatic level control circuitry, a method for limiting output power of said output amplifier, said method comprising:disabling said output amplifier and said automatic level control circuitry while awaiting receipt of a wireless downlink enable signal; receiving said wireless downlink enable signal from a RF controller; initializing said automatic level control circuitry responsive to receipt of said wireless downlink enable signal to a preset level such that output power of said output amplifier does not exceed a predetermined level when said RF-transmitter begins re-transmitting; and enabling said output amplifier following said initializing, wherein said output power of said output amplifier does not exceed said predetermined level, whereby said output amplifier is protected from saturation and possible damage from excessive power dissipation upon turn on.
