Abstract :
A novel diode tunable filter is described using quarter wavelength tapped stub resonator sections and digital microprocessor control. Fine resolution electronic tuning in 25KHz steps of a 2MHz-3dB transmission bandwidth from 270-400MHz was achieved with 50 watts CW RF power, 10dB average insertion loss and 42dB minimum rejection skirts, 6MHz from the center frequency.
