Abstract: An electronic device may include wireless circuitry having active circuitry such as active power splitter circuitry and active power combiner circuitry. The active power splitter and combiner circuitry can include single-ended or differential amplifiers coupled to one another using single-ended coupled lines or differential coupled lines. Each set of differential coupled lines may include first and second pairs of coupled lines. The single-ended coupled lines and the differential coupled lines can provide routing and impedance matching functions. In active power splitter circuitry, multiple transmitting amplifiers may be used to drive a plurality of antennas in a phased antenna array. In active power combiner circuitry, multiple receiving amplifiers may be used to receive radio-frequency signals from the plurality of antennas in the phased antenna array.

Abstract: An electronic device may include wireless circuitry having one or more radio-frequency amplifiers coupled to differential coupled lines. The differential coupled lines may provide routing and impedance matching for the radio-frequency amplifiers with minimal power loss. The differential coupled lines may include a first pair of coupled lines and a second pair of coupled lines. The first pair of coupled lines may include a first conductive routing path coupled to a first voltage line and a second conductive routing path routed along the first conductive routing path and coupled to a second voltage line. The second pair of coupled lines may include a third conductive routing path coupled to the first voltage line and a fourth conductive routing path routed along the third conductive routing path and coupled to the second voltage line.
