ELVA-1 High Power Pulse Noise Source
ELVA-1 high power noise sources employ specially designed silicon IMPATT diodes, operating in a pulse mode. It delivers the real incoherent radiation within 5 GHz bandwidth. 1 W level of output power allows to use the device for illumination of targets for the improvement of sensitivity of passive radiometers. The sources are available for all frequencies from 26 to 140 GHz. Low DC power requirements eliminate the need for complex high voltage supplies. The device is supplied with pulsed current source and triggering circuit. Both external and internal triggering modes are provided. Built-in digitally controlled generator allows to install repetition frequency within 10 Hz – 100 kHz range.
