<p>"RADIO FREQUENCY TRANSMITTERS" In a high power transmitter, more particularly a pulsed transmitter for a phase comparison navigation system, a plurality of solid state current control units are connected to respective separate sections of a primary inductance unit, these sections together forming a primary coupled to a secondary winding in the antenna circuit. The solid state control units may for example be switching units for timed switching of previously charged capacitors into resonant circuits. Switch controlled damping means may be provided for the tank circuits and antenna circuit in a pulse transmitter. Coil constructions are described permitting of the use of a large number of primary coil sections with separate current control units.</p> |
