WIDE BANDWIDTH RADIO FREQUENCY (RF) AMPLIFIER

摘要

An amplifier circuit includes an amplifier, a balun comprising a primary side having a primary inductance and a secondary side having a secondary inductance, the primary side coupled to an output of the amplifier, the secondary side coupled to a first output path of the amplifier circuit and a second output path of the amplifier circuit, a shunt inductance coupled to the first output path; and a compensating inductance in the balun, the compensating inductance coupled between a first node and a second node, the first node coupling the compensating inductance to the first output path, the second node coupling the secondary inductance to the compensating inductance.
