Abstract
A system for amplifying an input signal can comprise a main amplifier to amplify a delayed version of the input signal. The system can also comprise a peak amplifier to amplify the input signal upon the input signal reaching a threshold level and disable amplification upon the input signal falling below the threshold level. The system can further comprise a voltage combiner to electromagnetically couple the output of the main amplifier and the peak amplifier, such that an output impedance at an output node of the voltage combiner is a high impedance if the input signal is below the threshold level.

A system for amplifying an input signal comprising:
- a main amplifier to amplify a delayed version of the input signal;
- a peak amplifier to amplify the input signal upon the input signal reaching a threshold level and disable amplification upon the input signal falling below the threshold level;
- and
- a voltage combiner to electromagnetically couple the output of the main amplifier and the peak amplifier, such that an impedance between nodes at a given end of the voltage combiner is about zero if the input signal is below the threshold level.

- a coaxial cable to electromagnetically couple the output of the main amplifier and the peak amplifier.
A system for amplifying an input signal comprising:
- a main amplifier to amplify a delayed version of the input signal;
- a peak amplifier to amplify the input signal upon the input signal reaching about one quarter of a peak level of the input signal and disable amplification upon the input signal falling below about one quarter of the peak level;
- and
- a voltage combiner to electromagnetically couple the output of the main amplifier and the peak amplifier, such that an impedance between nodes at a given end the voltage combiner is about zero if the input signal is below the threshold level.
