Abstract :
An 18 GHz-band MMIC linearizer using a parallel diode with a bias feed resistance and a parallel capacitor has been proposed. This linearizer has weak positive gain deviation and its gain deviation can be controlled without changing phase deviation. By applying this linearizer to an 18 GHz-band power amplifier, an improvement of IMD3 of 20 dB has been achieved.
