BWO Tubes Description
Main
advantages of BWO tubes series BWO-xx are very smooth dependence
of output power versus frequency and high output power. Unique
technology applied for producing of BWO tubes allows to obtain
oscillations within a full waveguide frequency band without
deep points. We supply each BWO tube with a personal calibration
for output power versus frequency and frequency versus high
voltage dependencies. Operation frequency of BWO tube depends on high
voltage applied on a deceleration system of the tube - anode
voltage. Anode current can be controlled by means of a control
electrode - the grid that allows to control the output millimeter
wave power. The BWO tube allows to change frequency and power
independently and very fast - few microseconds for full band
frequency sweep and about 10 ns for on/off power modulation.

The
typical power/frequency and frequency versus high voltage
applied to deceleration system dependencies are shown on the
plots below for BWO-W model.
The
dependencies of output power versus anode current are presented
for 7 tubes on left plot below. The power measured on 100 GHz
frequency. On the right plot the dependencies of anode current
versus heating voltage are shown.
