Abstract: The present invention discloses an integrated single-body antenna-transceiver assembly for a multi-channel multi-point distribution system (MMDS) transceiver for bi-directional signal transmission and reception. The assembly comprises a dipole antenna-body comprising a surrounded plastic-molded exterior with interior metal dipole antenna extending vertically from a metal attachment-seat surrounding a signal feed pin connected to the dipole antenna. The assembly further comprises an MMDS transceiver having a transmitter printed circuit board (PCB) and a receiver PCB enclosed in a waterproof-metal housing having an antenna-attachment pad including a signal feed pin opening. The dipole antenna-body is securely attached to the waterproof-metal housing by attaching to the antenna-attachment pad sealed with an O-ring with the signal feed pin extended through the signal feed pin opening to contact the receiver PCB, the diplexer, and the transmitter PCB.

Abstract: The present invention discloses a frequency down converter for a multichannel multipoint distribution service (MMDS) television (TV) signal transmission and receiving system. The down converter system includes a separate address module for controlling signal reception for a subscriber according to a subscribing status carried by radio frequency signals transmitted from a signal transmission station. The address module includes a module container for containing a main circuit assembly therein. The down converter further includes a F-type connector for screwing onto the main circuit assembly through a connector opening of the module container for establishing an electric contact and for mechanically pulling the electric circuit assembly for sealing another opening on the module container.

Abstract: The present invention discloses an integrated dipole antenna and down converter apparatus. The integrated dipole antenna and down converter apparatus includes a dipole antenna for receiving microwave signals therein. The integrated dipole antenna and down converter apparatus further includes a down converter for receiving processed signals of the microwave signals from the dipole antenna for converting the processed signals to signals of lower frequency. The down converter includes main plate for supporting a tunable mechanical filter. The down converter further includes a tunable semi-mechanical filter supported on the plate. The semi-mechanical filter includes an upper circuit assembly and an identically symmetrical lower circuit assembly for canceling electromagnetic waves transmitting in the upper and lower circuit assemblies and the main plate whereby signal filtering efficiency is improved by reducing signal dissipation in the upper and lower circuit assemblies.

Abstract: The present invention discloses an inner module container provided for containing active circuit elements for processing and transmitting cable television signals receivable from and transmissible through pins of coaxial cables. The inner module container includes direct access openings for receiving coaxial cable pins for securely connecting to the active circuit elements whereby the pins of the coaxial cables are connected to the active circuit elements without requiring a separate connector outside of the inner module container. In a preferred embodiment, the active circuit elements further include mechanisms for locking coaxial cable pins for directly and securely locking to the coaxial cable pins.
