Abstract
A small and inexpensive mixer that does not require a choke inductor and a large-capacitance capacitor. The mixer has a FET. The FET's source is grounded via a capacitor and is also connected to a power-supply terminal. The FET's gate is coupled to a bias voltage and also connected to a gate input terminal via a capacitor. The FET's drain is connected to an output terminal via a capacitor. A modulating signal is input into the power-supply terminal, and a local signal is input into the gate input terminal, so that a modulated signal is output from the output terminal.
