Claim:
1. A method for performing radio based automatic level control for linear radio calibration, the method comprising: receiving, by a demultiplexer of a linear radio, a multiplexed plurality of signals from a second unit, the plurality of signals being communicated via a cable connecting the second unit with the linear radio; demultiplexing the multiplexed plurality of signals, by the demultiplexer, to produce a transmit signal of an intermediate frequency; receiving the transmit signal by a variable gain amplifier of the linear radio, the variable gain amplifier further receiving a signal from an operational amplifier, based on a signal indicating an amount of power of the transmit signal, and producing the transmit signal with a changed power gain; providing the transmit signal with the changed power gain to a coupler, the coupler providing the signal with the changed power gain to a mixer and a power detector simultaneously; and providing a second signal from the power detector to the operational amplifier, thereby forming a closed automatic level control loop.
