This paper presents the design and experimental characterization of a broadband hybrid high power amplifier (HPA) for L-band applications. The HPA has been optimized to work efficiently in the three sub-bands (E5, E6 and E1) dedicated to Galileo navigation system (f = 1192 ± 46 MHz, f = 1278 ± 25 MHz and f=1575±25MHz, respectively), showing promising results. The HPA exploits a hermetic packaged device with an active periphery of 25.4mm, developed in the 0.5μm gate length GaN/SiC HEMT process (GH50-20) available at United Mono- lithic Semiconductor (UMS) foundry. Experimental results shown output power even larger than 100W with associated power added efficiency and gain of 60% and 14dB, in more than a 35% of fractional bandwidth in L-Band. Indeed, the realized HPA shows very flat performance all along the frequency range from 1.14 GHz to 1.6 GHz, also achieving a quite good agreement between measurements and simulations.

Abstract
This paper presents the design and experimental characterization of a broadband hybrid high power amplifier (HPA) for L-band applications. The HPA has been optimized to work efficiently in the three sub-bands (E5, E6 and E1) dedicated to Galileo navigation system (f = 1192 ± 46 MHz, f = 1278 ± 25 MHz and f=1575±25MHz, respectively), showing promising results. The HPA exploits a hermetic packaged device with an active periphery of 25.4mm, developed in the 0.5μm gate length GaN/SiC HEMT process (GH50-20) available at United Mono- lithic Semiconductor (UMS) foundry. Experimental results shown output power even larger than 100W with associated power added efficiency and gain of 60% and 14dB, in more than a 35% of fractional bandwidth in L-Band. Indeed, the realized HPA shows very flat performance all along the frequency range from 1.14 GHz to 1.6 GHz, also achieving a quite good agreement between measurements and simulations.| File | Dimensione | Formato | |
