A method and apparatus for positioning a workpiece in a desired position on a gauge fixture. The apparatus includes a gauge fixture, a positioner assembly, a pusher assembly and a controller. The fixture has a first side and a second side, the first side being opposite the second side. The positioner assembly is mounted on the first side of the gauge fixture, and includes a stop member, a crank and a positioner sensor. The pusher assembly is mounted on the second side of the gauge fixture, and includes a pusher member and a pusher sensor. The controller is connected to the pusher assembly and the positioner assembly. During positioning, the pusher member of the pusher assembly pushes the workpiece until it reaches the stop member of the positioner assembly; the controller actuates the positioner sensor and the pusher sensor to sense the position of the workpiece on the gauge fixture and the controller actuates the crank of the positioner assembly to move the workpiece until the positioner sensor and the pusher sensor indicate that the workpiece is in the desired position. The positioner and pusher sensors are preferably removable and replaceable, such that when they are mounted they are located at known positions relative to a reference position of the gauge fixture. The workpiece may be placed against the stop of the positioner assembly initially, in which case the pusher member of the pusher assembly may be omitted.

Positioning system

A duplexer for a radio transceiver is disclosed in which two volumes of dielectric material each have at least two holes and each is covered with a conductive material except for one surface. An electrode on the one surface of each volume is coupled to one of the holes and is coupled to a substrate via a terminal passing through a mounting device. The substrate provides coupling between the terminals of the two volumes and a common antenna.

Multiple resonator dielectric filter

A dielectric block filter which may be mounted on a printed circuit board or other substrate as a single component is disclosed. The dielectric filter utilizes metalized hole resonators having coupling characteristics determined by the metalization pattern on one surface of the dielectric block. Input and output coupling is accomplished via terminals asymmetrically arranged in a mounting bracket. Mounting tabs on the bracket opposite a recessed area holding the dielectric block secure the filter to the circuit board and provide ground connection for the filter.
