Description
Diode frequency multipliers are widely used in small size solid-state signal sources for use in mm-wave range. Step-recovery and Schottky diodes are used as non-linear elements in the BFM-XX frequency multipliers. The frequency multipliers have multiplication factor 2 or 3 and can be assembled in series. To increase output power an intermediate power amplifier can be used between two multiplier stages. The highest operating frequency reaches 170 GHz at multiplication factor 9. Nominal input frequency is within 11 – 20 GHz frequency range and input power level up to 100 mW. The phase and amplitude stability of the output signal are defined by the quality of the pumping source. The input of a multiplier is a coaxial connector, and the output is a waveguide flange. A broadband millimeter-wave voltage controlled oscillator (mm-wave VCO) can be assembled using a BFM-XX multiplier and 11-20 GHz VCO.
