Abstract
An 8.2 Watt FET amplifier with 38.6 +- 0.5 dB gain over 17.7 to 19.1 GHz frequency band has been developed. This amplifier combines the outputs of eight multistage amplifier modules utilizing a radial combiner. This state-of-the-art uower leve has been achieved with a noise fiaure of less than 8.0 dB and AM/PM of less than 2°/dB. The third order intermodulation products at 1 dB qain compression were 20 dBc and variation in group delay over the frequency band was less than +-.25 nSec.
