An apparatus includes a microwave source that produces a microwave feed beam, and a first pair of microwave sensors that each intercept and receive a portion of the microwave feed beam. The two microwave sensors are spaced apart from each other along a first-pair axis. A first phase-comparison device has as it inputs the output signals of the two microwave sensors, and as an output a first phase comparison of the first-sensor output signal and the second-sensor output signal. A first geometrical calculator has as an input the first phase comparison and as an output a geometrical relationship of the first-pair axis to an other feature. This geometrical relationship output may be used to generate a control signal that is used to alter the geometrical relationship. There may be additional microwave sensors operating in a similar manner but spaced to provide information for other geometrical axes or allow improvements in geometrical measurements.

A millimeter wave power source module may include N submodules, each of which includes M circuit devices, where M and N are greater than one. Each circuit device may have an output connected to a corresponding radiating element. Each submodule may include a power divider having K input ports and M output ports, where K is a factor of M. Each input port may be coupled to a corresponding receiving element, and each output port may be coupled to an input of a corresponding circuit device. Each submodule may include a heat spreader for removing heat from the circuit devices. The power source module may include a combination RF feed network and heat sink. The combination RF feed network and heat sink may include a wavefront expander to expand the RF input wavefront along at least one axis, and to direct the expanded wavefront to the receiving elements of the N submodules. The combination RF feed network and heat sink may also include a heat exchanger thermally coupled to the heat spreaders of the N submodules.

A high power slide tuning capacitor () integrated into a circuit board adapted to function at RF and microwave frequencies. The capacitor () is comprised of a dielectric substrate () with a cavity () cut into a side of the substrate (); a ground plane () mounted on a bottom surface of the dielectric substrate (); a microstrip patch () mounted on a top surface of the dielectric substrate () and positioned above the cavity (); and a movable dielectric stub () which engages the cavity () such that a variable length of the stub () is positioned beneath the microstrip patch (). The microstrip patch () can be coupled to a desired circuit trace (), effectively forming a shunt capacitor to ground.

An apparatus for conveying an electrical signal includes: a conductive pathway having a conductive material. The conductive material has a first edge and a second edge and is configured to convey the electrical signal. The apparatus also includes a resistive material in contact with at least a portion of the conductive pathway, covering an edge of the conductive pathway, and extending beyond the edge. The resistive material has a conductivity less than the conductivity of the conductive material.
