ABSTRACT:
A wide bandwidth high-power T network tuner obtains its wide bandwidth operation by connecting a fixed capacitor between the input and ground, with the tuner using large, series connected variable capacitors for high power so as to solve the minimum capacitance problem on the higher frequencies, with the input and output matching capacitors being independent one from the other.
