    • A negative resistance generator includes first and second terminals; first and second inductors connected in series between the terminals; and a semiconductor amplifying device having a first control electrode connected to the first terminal and a first active electrode connected to the second terminal and a second active electrode connected to the junction of the inductors. When employed in an active filter resonator a first variable capacitor is interconnected with the inductors for setting the resonant frequency of the resonator. The resonators may be combined in an active filter with a transmission line where each of the resonators is interconnected to the line by decreasing resistance from the input to the output in order to balance the rf currents to which the resonators are subjected. An improved dual loop active filter control system is achieved by using a master oscillator that employs a resonator that is matched to the active filter resonator in the filter and servoing the frequency and Q-factor controls so that the drive signals are compensated for temperature drifts, manufacturing tolerances, and other problems while a buffer amplifier is used between the master oscillator and the frequency and gain control loops for isolating the master oscillator reference circuit from the loading of the loops and from the perturbation introduced by the frequency reference signal; a frequency shifting circuit in the frequency control loop permits the reference signal to be shifted to a lower or higher frequency than that of the master oscillator.

    • A distributed power amplifier includes a plurality of field effect transistors (FETS), each one of such FETS having gate, drain and source electrodes, such FETS having cascaded gate electrodes and cascaded drain electrodes successively coupled between an input terminal and an output terminal. The gate electrode of each one of the successively coupled FETS is coupled to the input terminal through a corresponding one of a plurality of capacitors, and a common bias source through one of a corresponding plurality of high impedance bias paths. Since the gate electrodes of each FET are coupled to the input terminal through a capacitor, the coupling capacitor in combination with the inherent capacitance of each FET provides a potential divider into each gate electrode. Therefore, the power fed to each gate electrode is selected by selecting the value of capacitance for the coupling capacitors. In an alternate embodiment, a pair of sets of such capacitively coupled FETS is provided with the drain electrodes of each set of such FETS being coupled to a common output r.f. transmission line.
