Abstract: Amplification circuitry is disclosed that couples neutralization transistors to amplification transistors to neutralize parasitic capacitance of the amplification transistors. Gates of a first amplification transistor and a first neutralization transistor are coupled together, and gates of a second amplification transistor and a second neutralization transistor are also coupled together. Drains of the first amplification transistor and the second neutralization transistor are coupled together, and drains of the second amplification transistor and the first neutralization transistor are also coupled together. Sources of neutralization transistors are coupled together at a node, such that a voltage swing of a first signal in the first neutralization transistor may be canceled by a voltage swing of a second signal in the second neutralization transistor. The node also couples to a resistor that prevents charge building in the neutralization transistors.

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.
