Abstract

A control circuit for a radar or sonar or other radiating system having a megatrol-high energy switch. The control terminal of the switch is coupled to the signal pulse source for the radiating system and the main electrodes of the switch are coupled in series with the radiating system output and the radiating element.

Claims

1. A controlled high frequency energy transmitter comprising:

a source of high-frequency energy;

a radiating element for said energy;

a high speed, high energy capacity switch connecting said source and said radiating element comprising;

a gas filled bidirectional discharge flash tube having a pair of main electrodes and a control terminal for initiating the firing of said tube;

a first diode;

said first diode being coupled in circuit with the energy source and the radiating element and the connection being coupled across said electrodes;

a high voltage pulse source;

means for actuating said pulse source coupled thereto;

means coupling said pulse source to said flash tube;

said coupling means comprising a capacitor having one side coupled to said pulse source and the other side coupled to one of said electrodes and to said terminal;

a second diode coupled to said pulse source;

a resistor coupling said diode to the other of said electrodes;

said first diode acting to block said pulse source from said energy source; and

said second diode acting to absorb transients from said capacitor when said flash tube switches on.
