“…GaN appears to be a superior candidate for the design of PAs when compared to GaAs and is becoming the technology of choice across frequency bands and markets. GaN amplifiers present a P sat the 36-46 -dBm range [106], [107], [108], [109], [110], [111], [112], while their GaAs counterparts are within the 34-40-dBm range [111], [112], [113], [114], [115], [116]. In addition, GaN PAs also show a superior PAE, which can surpass 40%, while GaAs PAs present PAEs of the order of 30%.…”

L ow-Earth orbit (LEO) constellations are revolutionizing the world of satellite communication (Satcom), providing new opportunities to manufacturers and operators and enabling innovative and attractive services to users. The main advantages of low-orbit satellite systems are • more extended coverage of the surface of Earth that permits the availability of Satcom links in areas not served by geostationary Earth orbit (GEO) systems • reduced latency that proves to be fundamental for real-time and mission-critical applications

“…Among them, PAs have occupied a dominant position. [8][9][10][11] Consequently, it is necessary for the designed MMIC PAs to possess excellent performance, such as large bandwidth, high efficiency, and good linearity as well as reliability.At present, most existing PAs related to the beautiful design and construction of buildings suffer from various limitations. Harmonic controlled amplifiers are no longer applicable due to very little efficiency improvement as…”

SummaryThis paper presents a broadband monolithic millimeter‐wave integrated circuit GaN power amplifier (PA) with arbitrary two‐port complex‐impedance matching method. The proposed matching topology has been applied to interstage matching network design by modifying traditional coupling matrix and synthesizing a desired network. The optimum load traction technique is introduced to provide some more suitable Zopts. After continuous‐wave test, the three‐stage MMIC PA achieves a peak PAE of 39.1% with a 34.9 dBm output power from 23 to 29.5 GHz and the measured S21 is 32.5 dB with a ±2.5 dB gain variation. When driven by a 400 MHz OFDM modulation signal with a PAPR of 8.5 dB, the measured ACPR is improved to −40.6/−40.7 dBc with DPD. In this case, the PA achieves an average PAE of 11.7% and a 26.7 dBm average output power.
