ABSTRACT:
A cascode radio frequency amplifier in which a control amplifier stage is provided and any number of clone amplifier stages are connected in series (cascode) with the control amplifier. The cascode amplifiers provide equal voltage and power since each of the clone stages provides unity gain. The device can operate from low frequencies to high frequencies.
