2KW LDMOS POWER AMPLIFIER

I have completed the 2KW version of the power amplifier. The power amplifier includes 2 pieces MRFX1K80 LDMOS FETs and several built-in sensors. The amplifier also contains several types of protection functions (too high current, too high swr, too high temperature, etc.).
Special thanks to Rainer DJ2RS for the QSO!!! If you need more information, write an email to me: hg7an.zoli@gmail.com Best 73, Zoli HG7AN

Просмотров 16 тыс.3 года назад

I completed another amateur radio project. I made a 600W LDMOS shortwave power amplifier. The most interesting thing is that the settings can be made on a 7-inch touch screen, and on this screen you can see a lot of useful information during operation, such as output power, temperature, SWR, and so on. The power amplifier includes 2 MRF300 LDMOS FETs and several built-in sensors. The amplifier ...
