20 W linear, high efficiency internally matched HBT at 7.5 GHz

An internally matched HBT has been developed for use in communications systems. An output power of 20 W with 6.5 dB gain and 40% PAE at 7.5 GHz was achieved. Over the 7.25 to 7.75 GHz band minimum output power was 16.5 W with minimum 38% PAE. Two tone testing showed good linearity.<<ETX>>
