Abstract
A baseband generator for pulses of high peak amplitude, rapid rise time, subnanosecond duration, and high pulse repetition frequency is disclosed. A plurality of capacitors are charged in parallel then discharged in series to cause a plurality of avalanche of transistors to fire sequentially. The resulting sum voltage across the capacitors is then applied to a step recovery diode to generate the pulse.
Claims7
An appartus for generating signals of short duration comprising:
- charging means having a conducting state and a nonconducting state for supplying energy at an output means thereof while in said conducting state and including a plurality of unidirectional current conductive devices poled to set said charging means to said nonconducting state when said energy supplied achieves a predetermined level;
- a plurality of chargeable energy storage devices coupled to said unidirectionl current conductive devices and said charging means such that all are charged from said charging means substantially simultaneously to achieve said predetermined energy level;
- switch means having a conducting state and a nonconducting state, and coupled to said plurality of energy storage devices for coupling said energy storage devices substantially in series when in said conducting state;
- and
- pulse shaper means coupled to said energy storage devices by said switch means during said conduction state of said switch means for providing an energy discharge path for energy stored in said storage devices and for providing an output signal representative of said energy discharge from said energy storage devices.
