Abstract: S-band broadband high power GaN internal matching technology was researched in the paper. The input and output impedance of the device were attained with load-pull and modeling technique, the broadband power divider / combiner circuit was realized by using binomial impedance transformer. The internally matched device demonstrates a continuous output power of more than 100 W and drain efficiency of over 45% with the maximum output power and drain efficiency of 150 W 65%, the power gain of over 9 dB between 2.0~4.0 GHz, at operating drain voltage of 28 V.

Key words: broadband, high power, internal matching
