Cable television multi-tap system
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.
Frequency independence for synthesis within programmable non-reciprocal network circuit
An apparatus includes parallel delay lines, each exhibiting a delay; a first set of switches for each port of a first set of ports, each of which is to selectively couple a port of the first set of ports to first ends of the delay lines; a second set of switches for each port of a second set of ports, each of which to selectively couple a port of the second set of ports to second ends of the delay lines. A signal source generates a series of clock signals that are sequentially time delayed between the first set of switches and the second set of switches, where an input signal at one of the first or second sets of ports travels from the one of the first or second sets of ports to an output port of opposite set of ports over the delay lines.

MODULAR CIRCUIT BOARD MULTI-TAP
A multi-tap device for a cable television (CATV) system includes a tap housing and a faceplate configured to be connected to the tap housing. The device also includes a first circuit board configured to be connected to the tap housing. The device also includes a second circuit board configured to be connected to the faceplate and to the first circuit board. The device also includes an access cover connected to the tap housing. The access cover is configured to be opened to provide access to disconnect the first circuit board from the tap housing and from the second circuit board and to subsequently remove the first circuit board from the tap housing, thereby changing a tap value of the multi-tap device. The second circuit board is configured to remain connected to the faceplate and positioned within the tap housing when the first circuit board is removed from the tap housing.
Modular circuit board multi-tap
A multi-tap device for a cable television (CATV) system includes a tap housing and a first circuit board positioned within and removably connected to the tap housing. A directional coupler is connected to the first circuit board. A faceplate is integral with the tap housing. One or more subscriber tap ports are connected to the faceplate. An access cover is connected to the tap housing. The access cover is configured to be opened to provide access to an interior of the tap housing for a user to disconnect the first circuit board from the tap housing.

Acoustic filter for antennas
Filter circuitry is used in communication systems that employ multiple antennas. In general, a communication system may have a transmit path and a receive path. The transmit path extends to a first antenna port and is configured to present signals for transmission in a first communication band and a second communication band to the first antenna port for transmission via a first antenna that is coupled to the first antenna port. The receive path extends to a second antenna port and comprises a first multiple passband/multiple stopband filter that provides a plurality of passbands and a plurality of stopbands interleaved with one another, wherein a first stopband and a second stopband of the plurality of stopbands correspond respectively to the first communication band and the second communication band and are separated by a first passband of the plurality of passbands.
