Abstract
A microwave frequency multiplier employs a first diode and a second diode each coupled in anti-parallel relationship across a signal input of a finline structure, each of the diodes being associated with signal-induced biasing elements for self biasing the diodes. A bias is caused to occur at internal nodes which increase with increased input power for a broad range of input power levels. The presence of such biasing results in waveform clipping at higher signal levels. Relative to prior art, the conversion loss will remain optimum up to high input power over an entire high-power input range. Additional external bias may be employed in alternative embodiments.
