摘要：

To meet the demands of advanced integrated electronic warfare systems with satellite communication modules, a 6-18-GHz monolithic microwave integrated circuit (MMIC) power amplifier (PA) with excellent harmonic suppression at 10 GHz was designed using a 0.15-mu m gallium nitride (GaN) high electron mobility transistor process. An elliptic filter output matching network was developed to improve the harmonic suppression of ultrawide-bandwidth high PAs in the satellite communication frequency band. Continuous-wave mode measurement results showed that the proposed PA can realize 41.1-44.1 dBm of saturated output power and 19%-40% of power-added efficiency at 6-18 GHz while achieving -30-dBc second harmonic suppression at 10 GHz. The proposed PA can alleviate the harmonic interference between an integrated electronic warfare system and Ka-band satellite communication module.
