Description:
For ssb， AM linear power amplifier， CW， FM power amplifier， And the most basic signal amplification expansionOverall gain of more than 40dB， which is 10，000 times， the input 1mW ， output 10WInput power 1-5mWOutput power 45W (max) (this data is the first test of the data， the new data below)Output Impedance: 50 Ohm， according to need adjustment between 10-200 EuroSuite size: 60 x 100mmInput and output interfaces: standard sma interfaces， external thread hole
By adjusting the V303 version of the time， the high-gain put up at 28MHz output power of 25W， basically squeezed out of the tube IRF530 potential. I personally tested the following data， this data table is a giant heat sink can withstand 200W measured above， and do not have sufficient cooling capacity of friends， please do not limit the work， so unsafe In 3-5MHz， due to the low frequency， low inductance， resulting in a gain of a certain loss of output power a little lower than 7MHz 3.500MHz 54W
7.050MHz 56W

10.000MHz 57W

14.270MHz 55W
