Abstract :
Feedforward compensation on a prototype 6-18-GHz amplifier that increases its second and third order intercept points is demonstrated. Measured performance improvement in both distortion and noise figure closely match theoretical predictions, with spurious signal cancellation of approximately=15 dB being observed. These results indicate the potential in utilizing the feedforward concept in future microwave systems applications.<>
