Abstract: A RF connector includes a first conductor and a symmetrical second conductor. Each conductor has an elongated structure of a flat conductive material with a length corresponding to ¼ of a nominal frequency of a signal to be coupled and is connected at a first end to a coaxial connector and at a second end to the housing. The RF connector can be switched between an ON state and an OFF state. In the OFF state, the first conductor is distant from the second conductor and in the ON state the first conductor is in close contact with the second conductor such that open sides of their respective housings are oriented against each other, and the conductors are facing each other.

Abstract: The invention relates to a directional coupler, coupling high power and low power is used to replace existing two high-power directional couplers, thus reducing the cost and reducing the insertion loss of high-power radio frequency channels. The directional coupler cooperates with a control conditioning board, a splitter, a multi-path radio frequency power amplifier and a combiner to form the radio frequency power amplifier system, and the system is connected to a spectrometer; on one hand, by using a standard signal output by the spectrometer and a feedback signal of the directional coupler, nonlinearity caused by the power amplifier is corrected to achieve magnet-free linear radio frequency power amplification and anomaly protection; and on the other hand, the spectrometer can be used for monitoring the output power of the directional coupler and monitoring antenna matching, so as to provide dual protection for the radio frequency power amplifier system.

Abstract: A radio frequency signal coupler includes an input port, an output port, a main transmission line coupled between the input port and the output port, and a coupled transmission line electromagnetically coupled to the main transmission line. The coupled transmission line includes a first transmission line, a second transmission line, and a switch configured to couple the first and second transmission lines during a first mode of operation and to decouple the first and second transmission lines during a second mode of operation. The radio frequency couple can be used in a front end module of a communications device, such as a mobile phone.

Abstract: A directional coupler includes a main line, a first sub line, a second sub line, a termination circuit, a first phase shifter circuit, a first selector switch, and a second selector switch. The termination circuit terminates one of the first sub line and the second sub line. The first phase shifter circuit is disposed on a first signal path between the first sub line and the second sub line. The first selector switch performs switching between connection and non-connection between the first sub line and the first phase shifter circuit. The second selector switch performs switching between connection and non-connection between the first phase shifter circuit and the second sub line.

Abstract: A symmetric dual direction coupler has a layout that is controlled such that there is an axis of symmetry between ports and that any switches used within the dual direction coupler are also symmetrical. That is, for a dual direction coupler having a transmitted port, an input port, an isolated port, and a coupled port with switches used to control forward mode or reverse mode for the coupler, the transmitted port and the input port are symmetrical across the axis of symmetry; the isolated port and coupled port are symmetrical across the axis of symmetry; and the switch layout is symmetrical across the axis of symmetry.

Abstract: A signal coupler (100) comprising: a main-transmission-line (114) that extends in a longitudinal direction within a substrate (102) between an input port and an output port; and a coupled-transmission-line (116) that extends in the longitudinal direction within the substrate (102) between a coupled port and a termination port. The coupled-transmission-line (116) is in a second layer (110). The main-transmission-line (114) comprises a first-portion (120) in a first layer (108), a second-portion (122) in a second layer (110), and a third-portion (124) in a third layer (112). At least part of the first-portion (120) is spaced apart from the coupled-transmission-line (116) in a depth direction. At least part of the second-portion (122) is spaced apart from the coupled-transmission-line (116) in the depth direction. At least part of the third-portion (124) is spaced apart from the coupled-transmission-line (116) in the depth direction.

Abstract: An apparatus includes a directional coupler and an absorptive low pass filter, in which the directional coupler has a first transmission line extending from a first port to a second port and a second transmission line extending from a third port to a fourth port, the first transmission line and the second transmission line configured such that a portion of a signal travelling from the first port onto the first transmission line is coupled to the second transmission line and towards the third port. The second port is connected to the fourth port of the directional coupler via the absorptive low pass filter. When the signal is input into the first port of the directional coupler and output through the third port of the directional coupler, the signal is substantially unattenuated if the frequency of the signal is in a passband of the absorptive low pass filter.

Abstract: Quarter-wavelength switchable directional coupler architectures and methods that that use intermediate terminated states during directional mode-switching events to prevent generation of reflection coefficients that cause spur generation. A first embodiment of the invention utilizes existing circuitry within a quarter-wavelength switchable directional coupler but alters the conventional mode-switching sequence by adding new stage sequences to effectuate intermediate terminated states to mitigate or prevent spurs. A second embodiment of the invention modifies existing circuitry within a quarter-wavelength switchable directional coupler by adding a cross-coupled intermediate-stage termination circuit, and alters the conventional mode-switching sequence by adding new stage sequences to effectuate intermediate terminated states to mitigate or prevent spurs. A third embodiment of the invention also modifies existing circuitry within a quarter-wavelength switchable directional coupler by adding dual independent intermediate-stage termination circuits, and alters the conventional mode-switching sequence by adding new stage sequences to effectuate intermediate terminated states to mitigate or prevent spurs.
