Radio frequency modulator device

A radio frequency modulator (1-3) arrangement comprises a baseband stage (1), a mixer stage (2) and a radio frequency stage (3). The baseband stage (1) comprises: an input line for receiving an input current (10) representative of a baseband input signal; baseband transistors (11, 12) passing some o...

Summary:A radio frequency modulator (1-3) arrangement comprises a baseband stage (1), a mixer stage (2) and a radio frequency stage (3). The baseband stage (1) comprises: an input line for receiving an input current (10) representative of a baseband input signal; baseband transistors (11, 12) passing some or all of the input current (10) between the first and second terminals thereof; an electrical connection (13) between the input line and the control terminals of the baseband transistors (11, 12); and an output line connected to the control terminal. A mixer stage (2) receives the signal (BBIp, BBIn) from the baseband stage (1) and mixes it with a radio frequency local oscillator signal to generate a radio frequency mixed signal (VRFp, VRFn). The radio frequency stage (3) receives the radio frequency mixing signal (VRFp, VRFn), applies the radio frequency mixing signal (VRFp, VRFn) to the control terminal of the radio frequency transistor (30, 31) such that it passes a radio frequency output current (IRFp, IRFn) be
