OB-XX series BWO tubes are very broadband and powerful
millimeter submillimeter sources cover 180-1100 GHz frequency
band. Unique technology applied for producing of sub-mm BWO tubes allows
to obtain oscillations within a full waveguide frequency band.
Operation frequency depends on high voltage applied on a deceleration
system of the BWO tube - the anode voltage. The construction of
the BWO tube allows to sweep the frequency very fast. Few microsecond
full band sweep is achieved in our laboratory. It is possible
also to adjust the frequency changing the magnetic field.
We supply each sub-mm BWO tube with a personal calibration for output
power versus frequency and frequency versus high voltage dependencies.
The dependence of frequency versus magnetic field is available
Minimal output power can be different for various tubes of
the same model.
The magnetic field should be provided in the following minimal
volume: d30 mm, L= 32 mm;
Tube d30 mm; Weight 0.3 kg. Water cooling.
dependencies of power versus frequency and frequency versus
high voltage applied to deceleration system are shown on the
plots below for OB-24 model:
is as one mentioned in the table, Uheating=6 ...
7 VAC, Heating Current 1-1.5 A typ, 2A max. Output waveguide
is oversized for all tubes. We also propose permanent magnets
for the tubes and appropriated power suppliers. Details of specifications
