A Novel Power Combining Network for Doherty Amplifiers

This article proposes a new type of power combining network for a Doherty amplifier based on the use of short transmission lines and lumped capacitors. Compared with the conventional combining network, which consists of λ/4 transmission lines, thi...

Modern mobile communication systems use band-limited linear modulation schemes, such as multi-level quadrature amplitude modulation (QAM) and quadrature phase shift keying (QPSK), which have high peak-to-average power ratio characteristics. For these systems, linear power amplifiers are needed to prevent adjacent channel interference. A power amplifier operated sufficiently below the...
