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.

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.

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.

Abstract: A computer disk assembly has a power supply-wiring harness unit and a disk pack unit for housing and mounting a hard disk drive. This disk drive is suspended within its housing on a vibration isolating suspension system which utilizes a plurality of spring steel coils, this suspension system being designed to isolate the disk from external vibrations and shock. The power supply-wiring harness unit is removably connected to the disk pack unit through a fastening system which includes an elongated plate member which slides into a channel formed in the bottom of the disk pack unit and a latching fastener member which is driven by a handle and engages a mating receptacle in the disk pack unit.
