摘要： An apparatus includes an amplifier circuit including a first transistor and a second transistor. The first transistor may include a gate having a gate oxide with a first thickness and a first gate length. The second transistor may include a gate having a gate oxide with a second thickness and a second gate length. The first transistor and the second transistor may be connected in a cascode configuration and the second thickness and the second gate length are greater than the first thickness and the first gate length, respectively.

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.
