A circuit includes an input port receiving an input signal having a first frequency. A phase-shifter network is coupled to the input port, receives the input signal, and produces therefrom first and second signals in quadrature with one another. Frequency multiplier circuitry has a common node and includes a first rectifier for rectifying the first signal to produce a first rectified signal having a second frequency that is twice the first frequency and to be applied to the common node, and a second rectifier rectifying the second signal to produce a second rectified signal having the second frequency and to be applied to the common node. A combination of the first and second rectified signals is available at the common node and includes harmonic contents at a frequency that is fourfold the first frequency.
