Patent ID: 6998941

Claim:
A frequency multiplier including an input circuit, embodied as a coaxial connector to input a signal to be multiplied, a means of supplying a signal to be multiplied to IMPATT diode mounted in a retainer, a means of supplying the diode with dc bias voltage and output waveguide frame, distinguished by the fact that the means of inputting a signal to be multiplied is embodied as a microstrip line formed on a polycore wafer and connected to a gold-plated strip which is connected by welding to the diode, the means of supplying the diode with dc bias voltage embodied as a quarter-wave filter formed by the microstrip inductance and capacitance, the output waveguide circuit is embodied as a waveguide T-bend with an IMPATT diode arranged at the centre, two short-circuiting pistons fitted in two opposite arms and a pass-band filter disposed in the third arm.
