A: Infineon IRF530N Q: How much power is there in the 10m band? A: The input is 5w and the output is over 43w. Q: Why do others use the IRF530 for very low power after 14mhz, but yours can reach 43w at 28.5mhz? A: Most hobbyists use IRF530 to design amplifiers, for input and output transformers do not spare good magnetic rings, while I use all original Fair-Rite magnetic rings, coupled with years of experience in RF circuit design, to ensure the high frequency band performance. Q: I see that the circuit supports MRF186, are replacement instructions provided? A: At the beginning of the design, I considered the compatibility of dual MOS RF tubes, such as MRF186 or MRF9120, after all, some enthusiasts hold a prejudice against IRF530, it is very easy to replace, experienced enthusiasts should read the circuit and can do the replacement, I will publish a replacement tutorial later when I have time. package ： 1pcx 50W Micro PA50 Shortwave HF Power Amplifier with Power SWR Meter and LPF Filter If you have any questions, please contact us in time, we will help you deal with the problem for the first time.
