Abstract :
Experimental results obtained from supercritical c.w. GaAs transferred-electron reflection amplifiers at about 34 GHz are reported. Gains in excess of 20 dB have been observed with typical (gain)¿Ãbandwidth products of 1.0¿1.5GHz. The best noise figure is 18 dB, and this parameter is shown to be sensitive to the doping profile. The output power for 1 dB gain compression is typically 2.5¿3.0 mW.
