  • Combiner probe providing power flatness and wide locking bandwidth
    Patent number: 4494087
    Abstract: A distributed inductive reactance is coupled to a terminating impedance at the interface of a combiner probe with a resonant cavity. The distributed reactance is implemented by a metal insert having a cavity interface and having a coupling portion, which is coaxial with a cylindrical dielectric and with a cylindrical cavity in an end of the terminating impedance.

  • TM coaxial cavity oscillator and power combiner
    Patent number: 4162458
    Abstract: In an oscillator or power combiner of the type operating at microwave, millimeter wave and above, apparatus for increasing the size, so that one or more active devices can be coupled to the oscillator, including a TM coaxial cavity operating at a predetermined frequency, which cavity has an output coupled thereto for removing power, and a second cavity operating at a dominant mode and coupled to the TM coaxial cavity, which second cavity assures efficient and spurious free operation of the oscillator or power combiner at the desired frequency.
