Filed:

Sep 3, 1996

Appl. No.:

8/707276

Inventors:

Jeffrey A. Paul - Torrance CA
Roy Wien - Cerritos CA
Douglas Klebe - Redondo Beach CA
Sergio Garcia - Hawthorne CA
Richard P. Mintzlaff - Granada Hills CA

Assignee:

Raytheon Company - Lexington MA

International Classification:

H01Q 300

US Classification:

343757

Abstract:

An integrated point-to-point microwave radio frequency unit/antenna system includes a microwave transceiver/antenna unit, a housing support element affixed to the microwave transceiver/antenna unit, and a mounting structure support element engaged to the housing support element. The mounting structure support element includes a fixedly adjustable ball-and-socket element, with either the ball or the socket affixed to the housing support element and the other affixed to an attachment structure. The mounting structure support element permits the microwave transceiver/antenna unit to be adjusted in three degrees of freedom.

Assignee:

Raytheon Company - El Segundo CA

International Classification:

H01Q 300
H01Q 112

US Classification:

343757

Abstract:

The radio frequency unit of a millimeter wave terrestrial radio includes a housing with a front face and a back face, a microwave radio frequency transceiver electronics package within the housing, an antenna affixed to the front face of the housing, and appropriate signal connections and feeds. One portion of a dovetail support structure, preferably the male dovetail fitting, is affixed to the back face of the housing. The other portion of the dovetail support structure, preferably the female dovetail fitting, is mounted to a mounting structure. The dovetail support structure allows the radio frequency unit to be readily mounted to and demounted from the mounting structure. A reference plane defined between the radio frequency unit and the mounting structure allows the radio frequency unit to be precisely oriented relative to the mounting structure.

International Classification:

H04B 138

US Classification:

455 73

Abstract:

An integrated point-to-point microwave radio frequency unit/antenna has a housing, a microwave antenna affixed to the front face of the housing, and a microwave radio frequency transceiver electronics package within the housing. The transceiver electronics package includes a circuit board having transmitter and receiver intermediate frequency processors. The transceiver electronics package further includes a microwave transmitter and a microwave receiver, each utilizing monolithic microwave integrated circuit architecture. The signals of the microwave transmitter and microwave receiver are preferably of different frequencies and are diplexed for communication with the antenna.

International Classification:

H01P 1207

US Classification:

333210

Abstract:

A waveguide evanescent mode filter is integrated with a monolithic microwave integrated circuit (MMIC) by forming both the MMIC circuitry and the waveguide filter on a single substrate that forms a common ground plane for both elements. The waveguide has a superstructure with an interior recess that is contoured to provide a desired cutoff frequency. The underlying portion of the ground plane can form the lower portion of the waveguide itself, and can also be contoured to define the cutoff frequency. Adjustable attenuation is provided by a resistive card that can be inserted by different amounts into the waveguide.
