摘要： The disclosure relates to a pre-5 th -Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond a 4 th -Generation (4G) communication system such as long term evolution (LTE). A Doherty power amplifier in a wireless communication system may include a differential carrier amplifier, a differential peaking amplifier, and an output matching circuit. The output matching circuit may include a primary tuning capacitor, a transformer, and a secondary tuning capacitor. The differential carrier amplifier may be connected to the primary tuning capacitor through a carrier capacitor, and inductors, of an output terminal of the differential carrier amplifier. The differential peaking amplifier may be connected to the primary tuning capacitor. The primary tuning capacitor, the inductors, and the carrier capacitor may be configured to function as a quarter-wave transformer.

摘要： Disclosed is a 5G (5 th generation) or pre-5G communication system for supporting a data transmission rate higher than that of a 4G (4 th generation) communication system such as long-term evolution (LTE). A transmission device comprises: a first amplification unit having a common source structure, including cross coupled capacitors, and amplifying an input signal; a second amplification unit, having a common gate structure, for amplifying a signal output from the first amplification unit; and a first removal unit which is connected to output terminals of the first amplification unit and input terminals of the second amplification unit and which removes at least one portion of second harmonics. The first removal unit can offset, with respect to a fundamental frequency, at least some of parasitic capacitance generated from the output terminals of the first amplification unit and the input terminals of the second amplification unit, and can ground a signal having a secondary harmonic frequency with respect to the secondary harmonic frequency.
