摘要:
A cable television apparatus includes a coupled-line directional coupler. The coupled-line directional coupler includes a coupled-line directional coupler body, an input side, an output side and a coupled side. The coupled-line directional coupler body receives a cable television video-audio-data signal through the input side or the output side. The coupled-line directional coupler body receives a high frequency signal through the input side. A frequency of the high frequency signal is higher than a frequency of the cable television video-audio-data signal. The coupled-line directional coupler body electromagnetically couples the high frequency signal to the coupled side. The coupled-line directional coupler includes a high pass filter function at the coupled side to filter out the cable television video-audio-data signal.

A directional coupler is configured to provide a forward and/or a backward signal derived from a high-frequency signal. The directional coupler comprises a coupling element coupled to a main line, wherein the main line is configured to transport the high frequency signal. The directional coupler further comprises a signal line connecting the coupling element to a measuring port. The signal line comprises a defected ground structure inserted between the coupling element and the measuring port.

摘要:
An apparatus comprising a first power combiner/divider network and a second power combiner/divider network. The first power combiner/divider network splits a first electromagnetic signal into split signals that are connectable to signal processor(s). The second power combiner/divider network combines processed signals into a second electromagnetic signal. The apparatus includes a three-dimensional coaxial microstructure.

Embodiments of coupler systems (10) include a directional coupler (12), a tuning element (14a, 14b), and an actuator (16a, 16b). The coupler (12) is configured to split an input signal into two output signals or, alternatively, to combine two input signals into a single output. The tuning element (14a, 14b) is a capacitive device that allows the frequency response of the coupler (12) to be varied, so that the coupler (12) can be tuned to a particular frequency or range of frequencies at a given operating condition. The actuator (16a, 16b) generates a mechanical force that actuates tuning element (14a, 14b).

A coupler assembly includes a monolithic body (5) with a bore (11) along a longitudinal axis. A coupler PCB chamber (7) with at least one coupler slot(s> (9) communicates between the PCB chamber and the bore. A coupler printed circuit board (15) is seated in the coupler PCB chamber. At least two couplers (17) are mounted upon the printed circuit board aligned generally parallel with the at least one coupler slot(s). A first side of each coupler may be coupled to a terminating load and a second side of each coupler may be coupled to a connection interface.
