Abstract
A radio-frequency modulator apparatus comprises a baseband stage, a mixer stage and a radio-frequency stage. The baseband stage comprises: an input line for receiving an input current representative of a baseband input signal, a baseband transistor that passes some or all of the input current between a first and a second terminal thereof, an electrical connection between the input line and a control terminal of the baseband transistor, and an output line connected to said control terminal. The mixer stage receives a signal from the baseband stage and mixes it with a radio-frequency local-oscillator signal to generate a radio-frequency mixed signal. The radio-frequency stage receives the radio-frequency mixed signal, applies the radio-frequency mixed signal to a control terminal of a radio-frequency transistor causing it to pass a radio-frequency output current between a first and a second terminal thereof, and outputs the radio-frequency output current as an output signal.
