摘要： An apparatus includes a plurality of transceiver circuits, each comprising one or more phase shifter circuits. The phase shifter circuits may be configured to make a phase change by switching at least one of a capacitance value and an inductance value in response to a control signal. A characteristic impedance and the phase of each phase shifter circuit are correlated such that after the phase change, a value of the characteristic impedance is maintained at a predefined value.

摘要： An apparatus includes a first circuit and a plurality of second circuits. The first circuit may be configured to generate a pair of quadrature signals from a radio-frequency signal. The second circuits may each comprise a plurality of cascode amplifiers. The cascode amplifiers may be connected in parallel. The cascode amplifiers may be configured to generate a plurality of intermediate signals by modulating the quadrature signals in response to a first control signal and a second control signal. The first control signal generally switches a contribution of the cascode amplifiers in the generation of the intermediate signal. The second control signal may adjusts a total current passing through all of the cascode amplifiers.
