A 10 GHz MMIC predistortion linearizer fabricated on a single chip is demonstrated for the first time. It employs less hybrid circuits compard with conventional devices, and is suitable for miniaturization. The total chip size of the fabricated MMIC is about 3.5 mm3.0 mm. The distortion reduction effect is examined using this linearizer. The improvement in IM3 is more than 15 dB between 10.45 GHz and 10.70 GHz, and more than 8 dB between 10.05 GHz and 10.90 GHz.
