Millimeter wave reconfigurable frequency multiplier circuit and control method thereof

Abstract

The invention discloses a millimeter wave reconfigurable frequency multiplier circuit and a control method thereof. A conventional millimeter wave frequency multiplier circuit can only realize certain frequency multiplication output of an input signal and cannot realize selection and output of a plurality of frequency multiplication frequencies. The millimeter wave reconfigurable frequency multiplier circuit comprises an input matching network based on a transformer, an amplification stage transistor, a frequency doubling transistor, a frequency tripling transistor, a capacitor, a resistor and an output reconfigurable matching network based on the transformer. The millimeter wave reconfigurable frequency multiplier circuit provided by the invention can realize selection and output of frequency doubling and frequency tripling of input signals and suppression of fundamental waves and other harmonic waves through the matching network and the bias voltage of the control transistor. The millimeter wave reconfigurable frequency multiplier circuit can be applied as a key module in a dual-frequency transceiver.
