Abstract
A switching amplifier for producing large output power signals, including a plurality of amplifier stages having signal inputs driven in parallel and series connected outputs. The amplifier stages amplify pulse signals representative of an input signal with as little distortion as possible in a wide frequency band, and in particular exhibit very high insulation and very low capacity. The amplifier stages therefore include switching amplifiers each including a transformer having a toroidal core of low remanence material, a secondary winding formed of plural turns of rf stranded wire wound on the toroidal core, an insulating housing surrounding the secondary winding, a primary winding formed of plural turns of rf stranded wire disposed on the insulating housing, an outer housing confining the transformer and being filled with an insulating material, and a metallic mandrel within the bore of the toroidal core.
