Abstract
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.
