Description
| _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 v
100 kHz range. |
Specifications
| VSWR
of the load should not exceed 2:1. Operating temperature
range -40-+50 ŚC. Specifications would be adjusted according
to customer's requirements. Please contact factory for
other frequency ranges, bandwidths, pulse lengths and
others. Device is designed in cylinder 120 mm length and
70 mm diameter. Special protection scheme is integrated
against an application of more then one triggering pulse
within 10 m s. To protect the diode the system ignores
all pulses during 10 m s period after the last triggering.
The device is supplied with built-in digitally controlled
triggering generator with variable repetition frequency
within 10Hz-100kHz. 256 values of repetition frequency
are available. The desired frequency would be installed
by dip switches or by 8bit TTL bus. Pulse duration would
be decreased optionally up to 5 ns using fast PIN switch,
FPS series. To control the amplitude of the source Voltage
Controlled Attenuator VCVA series would be supplied optionally.
