  • Patent number: 5440319
    Abstract: An antenna/downconverter directed to the subscription television distribution industry. The antenna/downconverter (20) includes an integral multidisc director mounted to a housing (51) which defines a reflector cup (54), side lobe suppression ears (38) and a chamber (66) which provides environmental protection for downconverter electronics (184). Received microwave energy is coupled to the downconverter electronics from the perimeter of a receive disc (50) axially spaced from the reflector cup. The housing defines a plurality of jaws (36) which facilitate alignment to variously polarized microwave signals when an installer receives a mounting mast in a selected one of the jaws.

  • Patent number: 5225799
    Abstract: A microwave filter (30) and method of fabrication in which an integral housing (22) defining a cavity (23) is formed from a blank (20) cut from a conductive sheet. The blank is bent to form the housing. The resultant housing includes resonators, resonator taps, tuning holes and tap apertures. Capacitance tabs and coupling tabs are added to the housing for tuning of the filter. The tabs are adjusted by access through the tuning holes in the blank. The blank further defines stops which align the taps with lines of a microstrip circuit when the filter is installed therein and grounding tabs for grounding to the microstrip ground plane. The filter may be in combline or interdigital configuration.
