Abstract: Using a 0.5 um process GaN HEMT power tube core with a total gate width of 36 mm, an S-band miniaturized internal matched power tube including choke circuit is designed by reasonably selecting the target impedance and optimizing the matching network. Under the working voltage of+48 V,-3.1 V and within 2.7~3.4 GHz, the output power of power tube is greater than or equal to 250 W, the power gain is greater than or equal to 12 dB, the power added efficiency is greater than or equal to 60%,and the size is only 15 mm×6.6 mm×1.5 mm, weight is only 0.6 g, shows excellent performance and has broad engineering application prospects
