    摘要： A directional coupler includes a first to a fourth port, a main line connecting the first port and the second port, a first and a second subline section configured to be electromagnetically coupled to the main line, and a phase shifter. The first subline section, the phase shifter, and the second subline section are arranged in this order in series between the third port and the fourth port. The phase shifter outputs a signal that is phase-delayed relative to an input signal. The phase delay amount of the output signal of the phase shifter relative to the input signal increases with increasing frequency of the input signal. A frequency twice as high as the frequency of the input signal at which the phase delay amount is 90 degrees is lower than the frequency of the input signal at which the phase delay amount is 180 degrees.

    摘要： A 90-degree hybrid circuit includes a dielectric substrate, a first conductor that includes a conductor pattern formed on the dielectric substrate and electrically conducts between a first port and a second port, a second conductor that includes a conductor pattern formed on the dielectric substrate and electrically conducts between a third port and a fourth port, and a coupled line comprising a portion of the first conductor and a portion of the second conductor that face each other on front and back sides of the dielectric substrate. A first coupled line portion as the portion of the first conductor includes a coplanar line with first ground patterns formed to sandwich the first coupled line portion from both sides. A second coupled line portion as the portion of the second conductor includes a coplanar line with second ground patterns formed to sandwich the second coupled line portion from both sides.

    摘要： Approaches, techniques, and mechanisms are disclosed for allowing multiple distinct and diverse wireless services (e.g., Wi-Fi, Bluetooth, Radio Frequency for Consumer Electronics (RF4CE), ZigBee, etc.) to share common frequencies while utilizing a single set of antennas. Among other potential benefits, the techniques may permit the sharing of common frequencies amongst multiple services with reduced (or no) interference amongst the services relative to conventional designs, which, depending on the embodiment, may increase performance, improving manufacturability, save design and material cost, and so forth. According to one embodiment, a multi-input directional coupler printed circuit may be implemented for multiple wireless services. This device may include a single directional coupler with reduced or no loss, placed in series with two combiners that provide high isolation for wireless signals. The device may thus allow multiple wireless services with potentially different protocols to share the same or different frequency bands using a single antenna.

    摘要： The auxiliary ground layer is a part in which the main line and the sub line do not overlap in the lamination direction and is disposed to face a part in which a distance from the first ground layer and a distance from the second ground layer are different in the lamination direction. When a longer distance is set as a first distance a and a shorter distance is set as a second distance b between a distance between the non-overlapping part and the first ground layer and a distance between the non-overlapping part and the second ground layer, and a third distance between the non-overlapping part and the auxiliary ground layer is set as c, the relationship of a>c≥b is satisfied.

    摘要： Directional couplers having a chain configuration and devices incorporating same. In some implementations, a chain coupler assembly can include a plurality of couplers each having a driver arm configured to route a respective RF signal and a coupled arm disposed physically proximate to the driver arm to detect a portion of power of the respective RF signal. Portions of the driver arm and the coupler arm can form an overlapping region. At least one of the driver arm and the coupled arm can have a non-straight arm shape, and the coupled arms of the plurality of couplers can be connected together in series.
