Abstract : The patent describes the amplitude modulation of a radio frequency. Minimum distortion and good linearity is accomplished by driving a squaring circuit of the alternately conducting two transistor type at the radio frequency while using the audio signal to control amplitude of the square wave output. Bridge and differential amplifier feedback means are used to assure 50% duty cycles for the squaring circuit transistors.
