Described is a transformer wherein the primary winding is formed from the same unitary piece of electrically conductive metal that comprises the housing of the transformer.

Transformer with a one-piece primary winding and housing

Described is a transformer having a two-piece primary winding and housing wherein the second piece is mechanically received within the first piece and electrically coupled together.

Transformer with a two-piece primary winding and housing

Provided is a modulator having two amplifying stages for supplying high-voltage pulses to the primary winding of a transformer connected to a microwave transmitter tube. The first stage uses field-effect transistors connected in a common source configuration to amplify input pulses to drive the second stage, which uses field-effect transistors connected in a common gate configuration to drive the transformer. The circuit configuration provides a large voltage swing across the transformer primary and a short transistor switching time.

Microwave tube modulator

A method for packaging components in the primary circuit of a microwave tube modulator output transformer. Modules are assembled using parallel plates upon and around which transistors and other necessary components are mounted. In addition to providing mechanical support for the components, the plates act as conductors for circuits common to respective elements of paralleled transistors, thereby minimizing electrical resistance and inductance in the primary circuit. The modules are designed to mount to the output transformer such that two of the parallel plates are mechanically connected to the respective two ends of the transformer primary, and a number of modules can be mounted around and to one transformer according to the amount of energy required.
