摘要：
This paper presents the design and experimental characterization of a Doherty power amplifier cell targeting the satellite Ka-band downlink. The foreseen application is in a combined power amplifier, where two Doherty cells are combined in parallel to achieve power levels of the order of 6W. The measured performance of the DPA cell well compares with the present state-of-the-art for the application, with output power in excess of 34dBm in the 17.3-20.3GHz band, gain around 12 dB, and efficiency higher than 25% and 20%, at saturation and 6 dB output power back-off, respectively.
