US Patent:
52085546, May 4, 1993
Filed:
Jan 24, 1992
Appl. No.:
7/825194
Inventors:
Harvey Endler - Van Nuys CA
Hadi Mojaradi - Los Angeles CA
Assignee:
Systron Donner Corporation - Sylmar CA
International Classification:
H03F 368
US Classification:
330295
Abstract:
A Class A high power amplifier having an operating frequency in the range of less than substantially 2 GHz and suitable for aircraft use, is all solid state in that gallium arsenide field effect transistors are utilized. These are mounted in a large copper heat sink which is air cooled to provide for overall cooling by conduction and convection. By the use of microstrip matching circuits, the relatively low impedance of the gallium arsenide FET units is matched to the required higher system impedance. At the same time a 40% band-width is provided due to the superior matching.
