Abstract: A very wide band high-frequency modulator is disclosed using ring-connected diodes in which the local oscillator and the signal frequency can be very different from each other. The modulator is doubly balanced and uses two wide band phase inverters connected across conjugate diagonals of the ringconnected diodes and a balanced to unbalanced output connection.
