Varactor multiplier including input circuit for increasing band of operation
Abstract
Abstract A VARACTORMULTIPLIER HAS AN INPUT CIRCUIT INCLUDING A SECONDARY CIRCULATING CIRCUIT COMPRISED OF AN INDUCTOR AND A CAPACITOR WHICH ARE TUNED TO A FREQUENCY NEAR THE SECOND HARMONIC OF THE INPUT FREQUENCY THEREBY PROVIDING A NET CAPACITANCE AT THE INPUT FREQUENCY WHICH LOWERS THE COMPOSITE RESONANT FREQUENCY OF THE MULTIPLIER SO THAT ITS BAND OF OPERATION IS INCREASED. THE SECONDARY CIRCULATING CIRCUIT ALSO PROVIDES A NET INDUCTANCE AT HARMONIC FREQUENCIES OF A HIGHER ORDER THAN THE SECOND THEREBY DESENSITIZING THE MULTIPLIER TO TUNING AND TEMPERATURE CHANGES OF THE OUTPUT AND IDLER CIRCUITS. FURTHERMORE, THE SECONDARY CIRCULATING CIRCUIT FORMS PART OF THE IMPEDANCE TRANSFORMATION NETWORK WHICH MATCHES THE VARACTOR TO ITS DRIVER.
