 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 170GHz at multiplication factor 9. Nominal input frequency is within 11GHz - 20GHz 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 broad band millimeter-wave voltage controlled oscillator (mm-wave VCO) can be assembled using a BFM-XX multiplier and 11-20GHz VCO.
