Patent
Radio Frequency Simulation Systems, Inc. | Date: 2013-06-03

Orthomode transducers (OMTs) and methods of fabricating OMTs are disclosed. According to disclosed embodiments, an OMT includes a housing defining an internal waveguide. The housing may be composed of a first cast housing member attached to a second cast housing member. The first housing member may include a first side of the waveguide that is cast into the first housing member. The second housing member may include a second side of the waveguide that is cast into the second housing member. A method of fabricating an OMT may include arranging at least one casting insert in at least one mold, casting the housing in the mold and casting a waveguide in the housing using the at least one casting insert. The disclosed devices and methods provide cost effective solutions for fabricating OMTs of various operating frequencies that share a substantially similar outer housing shape and size.

Difficulties in grounding a non-integral, deep drawn resonator (DDR) to the filter body of a cavity may be substantially eliminated by preventing the movement of the DDR away from a grounding contact area on the filter body. The addition of a compression plate and stop limiter in the connection of the non-integral DR to the filter body helps insure that any such movement is eliminated or substantially reduced.

As EW needs to be smaller, lower power, and higher performance, there is a strong push by the US Government to create new technologies to achieve the ever changing goals of our future warfighters in the EW battlespace. With clocking speeds of digital devices encroaching tens, if not hundreds of gigahertz, the opportunity to create a Digital Radio Frequency Memory (DRFM) exclusively from these components is upon us and the benefits of higher performance, wider operational bandwidths, lower cost and extremely high reliability are the additional anticipated benefits of this US Navy SBIR topic. As Radio Frequency Simulation Systems (RFSS) matures and begins fielding this technology through the support of the USN at Pt. Mugu, the need for expensive and bulky wideband RF converters and their associated agile frequency schemes will fade away. RFSS, the winner of the Phase I topic and selected for the Phase II program, is a subject matter expert and supplier of DRFMs and DRFM based systems including jammers and radar test equipment. The innovative approach developed by RFSS will be discussed against the backdrop of currently fielded technology showing the benefits of the Direct to Digital DRFM approach for the US Government and EW industry.

Antenna array calibration systems and related methods include or utilize a plurality of signal splitter/combiner networks. Each of the signal splitter/combiner networks has a calibration signal sampling point in electrical communication with a signal input point, and signal output points. Each calibration signal sampling point may be capacitively coupled to a respective calibration source input of a calibration network. The signal splitter/combiner networks may be formed as phase-shifting networks.
