1. A method of powering up an amplifier system having first and second amplification chains, wherein signal outputs of the first and second amplification chains are combined to produce an output transmission signal, the method comprising:

  • (a) applying a first signal to the first amplification chain and a second signal to the second amplification chain, wherein the first and second signals are substantially in antiphase to inhibit emissions from an antenna;

    (b) adaptively predistorting the first and second signals until a desired level of balance is reached between the first and second amplification chains;

    (c) increasing amplification power levels of the first and second amplification chains by an incremental amount and repeating (b); and

    (d) repeating (c) until an operational power level is reached.
