Abstract :
The letter discusses how the intermodulation distortion in impatt diode amplifiers can be improved significantly by active compensation. Theoretical evaluation based on a large-signal impatt diode model predicts considerable improvement in the intermodulation behaviour; in particular, the improvement in the third-order intercept point is found to be in excess of 12 dB.
