15W Hybrid GaN Power Amplifier through Microstrip Radial Stub 4W GaN MMIC for X-band Radar ApplicationsPublished in Institute of Electrical and Electronics Engineers Inc.
2020
Radar Front-Ends crave diverse power amplifiers, which must be small-scaled, productive and economical. Our approach elaborate optimized Design of high power GaN power amplifier adopting microstirp radial stub in pair input and output matching network for an X-band Radar applications that overlay 8.5 GHz to 9.5 GHz.To develop 15W power amplifier utilizing a compact design of 4way power divider with proposed design was accomplished in microstrip technology adopting radial stub for the superior matching. The system achieves a 15W (43 dBm) output power from a 23 dBm input drive with a 42% Power Added Efficiency (PAE) and a 20 dB gain in CW-mode operation with a 28V drain voltage. The 4W MMIC design was completed on the 0.25μm gate length GaN on SiC process of UMS (GH25) using Keysight ADS 2017 with die size of 1.8 x 2.4 mm2. The proposed 15W power amplifier through a design of 4W MMIC in GaN GH25 and power divider/combiner mounted on printed circuit board consumes an area of 55 x 24 mm2. © 2020 IEEE.
