| Abstract(in English) | A 26-W X-band high efficiency GaN MMIC power amplifier with compact spurious suppression filters is presented. GaN MMIC power amplifier has been utilized in many applications such as base-stations for communication systems and radar system due to its high power density and efficiency. FETs are operated in saturation output power and undesirable harmonic spurious is generated. Therefore an off-chip low pass filter are usually necessary in a transmit module to satisfy spurious specifications. However, filters causes loss and increase of size and cost to satisfy spurious specification. Here, a GaN MMIC power amplifier with compact spurious suppression filters is proposed and developed. They work not only as a band rejection filter but also as a matching circuit to obtain optimum harmonic impedance for FETs to improve efficiency. Measurement results of the developed two-stage amplifier shows output power of 26 W, power added efficiency (PAE) of 55 %, associate gain of 20 dB and the second harmonic spurious of less than -43 dBc. This result is comparable with the state-of-the-art X-band MMIC power amplifiers ever reported. |
