    Abstract: A power combiner circuit comprises a network topology for broadband RF and microwave systems that includes coupling elements, internodal matching sections, and an output matching section. The network topology serves as a combining mechanism for power from multiple power amplifiers. The network topology is designed so that characteristic impedances of transmissions lines serving as the coupling elements, internodal matching sections, and an output matching section produce a load impedance at an output port that is matched to the impedances seen by each power amplifier providing power to the power combiner circuit. Such a network topology is scalable to an unlimited number of power amplifiers, and enables a desired broadband frequency response for power amplification, while realizing a very low level of power output loss between input and output ports.

The tunable filters are fabricated within the same integrated circuit package as the associated frequency based circuitry, thus minimizing R, L, and C parasitic values, and also allowing residual and other parasitic impedance in the associated circuitry and IC package to be absorbed and compensated.

  • Patent number: 10396830
    Abstract: Apparatus and methods for front-end systems with multiple loopbacks and a shared back switch are provided. In certain configurations, a front-end system includes a first transmit path between a first transmit port and an antenna port, a second transmit path between a second transmit port and the antenna port, a first loopback path from the first transmit path to a receive port, and a second loopback path from the second transmit path to the receive port. The first and second loopback paths operate with a shared back switch to reduce area and/or complexity of the front-end system. Additionally, each loopback path includes a loopback selection switch that operates in combination with the back switch to select that particular loopback path.

  • Patent number: 10396908
    Abstract: An impedance matching network between a transmitter and an antenna. The impedance matching network comprises of a watt meter coupled to the transmitter for measuring a standing wave ratio (“SWR”). A first unbalanced to unbalanced transformer (“first unun”) with an impedance ratio of N:1 is selectively coupled in series with the watt meter. A microprocessor is coupled to the watt meter for determining iteratively whether the first unun lowers the standing wave ratio (“SWR”) in response to switching the first unun in and out of a series connection with the antenna.

  • Patent number: 10348365
    Abstract: The invention relates to a directional coupling communication apparatus where the coupling impedance can be easily matched to reduce reflections, and thus, the speed of communication channels is increased as compared to that with inductive coupling, and at the same time, the reliability of communication is improved by increasing the signal intensity. Modules having a coupler where an input/output connection line is connected to a first end, and either a ground line or an input/output connection line to which an inverse signal of a signal to be inputted into the input/output connection line connected to the above-described first end is inputted is connected are layered on top of each other so that the couplers are couplers to each other using capacitive coupling and inductive coupling.
