  • Patent number: 11888504
    Abstract: An electronic device may include signal transmission circuitry such as wireless circuitry having a signal source, a signal path, and an output node coupled to an output load. The signal source may transmit a signal to the output load over the signal path. The output load may have an impedance characterized by a first reflection coefficient. A signal coupler may be disposed on the signal path. A power detector coupled to a coupled node of the signal coupler may measure a voltage at the third node. A termination coupled to an isolated node of the signal coupler may include components that cause the termination to exhibit a second reflection coefficient. The second reflection coefficient may be selected to configure the voltage at the third node to track a power wave at the output load to within a constant that is invariant as the first reflection coefficient changes over time.

  • Patent number: 11821930
    Abstract: Low loss high directivity wire couplers use a transmission airline structure and a low diameter coaxial cable ending in a wire loop sensor, which is inserted into an elliptically formed conical opening of the ground wall of the transmission line and protrudes into its cavity leading into a coupled and an isolated port. Lower, capacitively induced, electrical currents, because of the protruding ground edges of the conical or recessed openings, compared with the unperturbed antiphase magnetically induced currents, lead to controlled higher directivity in a frequency range up to at least 170 GHz.

  • Patent number: 11711068
    Abstract: A phase shifter for altering the phase of a radio frequency signal is disclosed herein. A Lange coupler is used having reflective ports that are coupled to artificial transmission lines. The artificial transmission lines provide a reflection transmission path, the length of which can be determined by digital control lines. Transistors placed along the length of the central trace provide independent paths to ground that serve to shorten the electrical length of the ATL. Accordingly, by selectively turning the transistors on/off, the electrical length of the ATL can be selected and thus the amount of phase delay introduced by the phase shifter.

  • Patent number: 9905901
    Abstract: Differing from conventional directional coupling device being implemented on a coin-like planar board, the present invention stacks a bottom substrate, at least one phase retarding unit, at least one reference ground unit, a coupled circuit layer, a main circuit layer, and a top substrate to form a miniature directional coupling device. Because this miniature directional coupling device not occupies too much circuit area when being applied in a mobile communication product, the miniature directional coupling device can meet the requirements of light weight and compact size demanded by high-technology mobile communications for the electronic components. It is worth explaining that, since the said phase retarding unit consists of many end-to-end connected transmission wires, engineers skilled in designing microwave circuit are able to carry out the modulation of coupling flatness of the miniature directional coupling device by changing a total length of the end-to-end connected transmission wires.

  • Patent number: 9312592
    Abstract: An adjustable directional coupler circuit includes a directional coupler and a correction circuit. The directional coupler includes a first port for receiving an input signal; a second port for outputting the input signal to a load; a third port for outputting a first coupled signal including a desired first coupled signal proportional to forward power of the input signal and an extraneous first coupled signal proportional to reverse power of a reflected signal; and a fourth port for outputting a second coupled signal including a desired second coupled signal proportional to the reverse power and an extraneous second coupled signal proportional to the forward power. The correction circuit adjusts magnitude and phase of a sample of the second coupled signal to provide an adjusted second coupled signal, and to sum the adjusted second coupled signal and the first coupled signal to cancel the extraneous first coupled signal.

  • Patent number: 9077305
    Abstract: Semiconductor dies and methods are described, such as those including a first capacitive pathway having a first effective series resistance (ESR) and a second capacitive pathway having an adjustable ESR. One such device provides for optimizing the semiconductor die for different operating conditions such as operating frequency. As a result, semiconductor dies can be manufactured in a single configuration for several different operating frequencies, and each die can be tuned to reduce (e.g. minimize) supply noise, such as by varying the ESR or the capacitance of at least one of the pathways.
