    Abstract: A microwave oscillator using a Gunn diode in a section of rectangular waveguide tuned to resonate as a cavity to a fundamental frequency that is below the waveguide cutoff frequency has its output for the fundamental frequency located at a place in the cavity at which a peak of the fundamental frequency wave and a null of the second harmonic coincide. Fundamental frequency output is taken in a direction transverse to the axis of the waveguide. Harmonic frequency energy can also be taken from the waveguide section, or suppressed, as desired.

    Abstract: Disclosed is an improved and highly efficient coaxial TRAPATT oscillator and method for rapidly tuning same. The oscillator includes a TRAPATT diode connected directly between an outer coaxial conductor and a cylindrical quarter wave impedance transformer, and the transformer is in turn coaxially mounted directly between the TRAPATT diode and an inner coxial conductor of the oscillator. An end wall of the cylindrical impedance transformer is closely adjacent to the TRAPATT diode and it forms with the outer conductor a relatively large capacitance necessary for handling the TRAPATT diode displacement currents. Additionally, the geometry of the impedance transformer may be varied to control both this capacitance as well as the transformer impedance, ZT, and the latter in turn determines the optimum delay angle for the oscillator. The impedance transformer provides, among other things, the three functions of: (1) impedance matching the TRAPATT diode to the coaxial oscillator circuitry, (2) providing Saalbach; Herman Karl relatively large gap capacitance, Cg, necessary for handling TRAPATT diode displacement currents, and (3) controlling the optimum delay angle, theta d, of the oscillator. The geometry and location of the step transformer with respect to the TRAPATT diode and the above coaxial conductors greatly improve the tunability of the oscillator.

    Abstract: A microwave oscillator includes a metal housing which defines a cavity in which microwave radiation is produced by an internally mounted Gunn diode or the like. A tuning member projects into the microwave cavity through a hole formed in a wall of the oscillator housing. Depending on the length of its projection into the cavity, the tuning member controls the frequency of the microwave energy produced by the oscillator. The tuning member is supported on the cavity housing by a mounting member made from a material having a relatively high coefficient of thermal expansion. Particularly preferred materials include polymers such as polyethylene and polypropylene. Preferably, a microwave filter or choke is provided to reduce the leakage of microwave energy from the cavity through the hole in the oscillator housing. Such a choke comprises a pair of capacitors separated by an inductor. These elements are defined by (a) a portion of the oscillator housing, (b) the tuning screw (which is given a special cross-sectional contour), and (c) a sleeve of dielectric material, such as Teflon, which surrounds the tuning member.

    Abstract: A microwave oscillator having very low phase noise characteristics has a reflection oscillator circuit coupled to a right-circular cylindrical resonant cavity designed to operate in the TE.sub.011 mode. The resonator length L and inner diameter D are restricted to a range of values such that (D/L).sup.2 is less than 2.5 but greater than 1.7. To suppress the TM.sub.111 resonant modes in the resonator, two techniques are employed. A single tuning post is disposed on either resonator end plate at a point where the TM.sub.111 electric field Z-component is a maximum. The post length is adjustably fixed to maximize the output microwave power at the cavity output port. Each end plate also has a continuous gap separating each plate from the housing to suppress electric field currents of the TM.sub.111 mode flowing on the inner surface of the resonator.
