摘要： A cable television (CATV) multi-tap system includes a tap housing. The system also includes a face plate including one or more subscriber ports. The system also includes a circuit board positioned within the tap housing and coupled to the face plate. The system also includes an access cover coupled to the tap housing. The access cover is configured to be removed from the tap housing to allow access to the circuit board without removing the face plate or the circuit board from the tap housing.

摘要： Degrees of a change in an insertion loss of a main line and a change in a phase of a signal are small regardless of whether or not detection is performed by using a sub-line. A directional coupler includes a main line, a sub-line, a first termination circuit, a second termination circuit, and a switch. The sub-line has a first end and a second end. The first termination circuit terminates the first end and the second end of the sub-line. The switch switches connection and disconnection between the sub-line and the first termination circuit.

摘要： The high-directivity directional coupler of the present invention allows the coupler to maintain high-directivity when the stripe line distance between the mainline metal segment and at least one coupling metal segment is relatively large, to avoid material breakdown by a strong electric field under high-power operation, and is suitable for accurate power measurement in high-power RF systems.

摘要： A branch-line coupler of reduced size but comparable performance includes a first transmission line, a second transmission line, a first bent transmission line, and a second bent transmission line. The first transmission line includes a first strip transmission line, a first branch transmission line, and a second branch transmission line. The first strip transmission line extends along a predetermined direction, the first and second branch transmission lines being slotted. The first and second branch transmission lines are symmetrical around a first axis and around a second orthogonally-disposed axis. The first bent transmission line is electrically connected to the terminals of the first and second transmission lines on one side, and the second bent transmission line is electrically connected to the terminals of the first and second transmission lines on the other side.

摘要： A directional coupler includes a main line, a sub-line electromagnetically coupled with the main line, a coupled output terminal, plural filters, filter switching circuits, and plural filter protecting switches. Each of the filter switching circuits is able to connect a corresponding one of the plural filters to one end of the sub-line and to the coupled output terminal. Each of the filter protecting switches is directly connected to a corresponding end of a corresponding one of the plural filters and is able to switch between a connection state and a disconnection state. The connection state is a state in which the corresponding end of the corresponding one of the plural filters is connected to a reference potential. The disconnection state is a state in which the corresponding end of the corresponding one of the plural filters is disconnected from the reference potential.

摘要： A directional coupler (10) includes a main line (11), a sub-line (12), and a termination circuit (13) that is connected to one end (121) of the sub-line (12), and further includes an adjustment terminal (ADJ), as a lead-out terminal, that is led out from a node (N) between the one end (121) of the sub-line (12) and the termination circuit (13). The termination circuit (13) may be formed of a circuit in which a capacitance element (131) and a resistance element (132) are connected in parallel with each other, a capacitance value of the capacitance element (131) may be smaller than a capacitance value with which the directivity of the directional coupler (10) is optimized and a resistance value of the resistance element (132) may be larger than a resistance value with which the directivity of the directional coupler (10) is optimized.
