FIELD: superhigh-frequency engineering. SUBSTANCE: frequency multiplier has cascaded input and output microstrip filters and varactor diodes connected in parallel to them. Output cavity of input filter also functions as input cavity of output filter; one or both halves of its strip conductor is shorted out to ground through varactor diodes. First resonance frequency of input filter output cavity equals input-power frequency; second resonance frequency equals output-power frequency. First resonance frequency of input-filter input cavity equals input-power frequency; third resonance frequency is higher than output-power frequency; input power is applied to voltage node point at second-cavity frequency. Second resonance frequency of output-filter output cavity equals output-power frequency; output power is picked off cavity at voltage node point at input-power frequency. First resonance frequency of output-filter output cavity equals output-power frequency. EFFECT: reduced number of components due to more effective their use (narrow-band frequency multiplier may incorporate only one microstrip cavity); reduced size of device. |
