2sc1971 has long been Stop production, so this version uses disassemble parts, please note that before you buy it.
For ssb, AM linear power amplifier, CW, FM power amplifier, And the most basic signal amplification expansion
Overall gain of more than 40dB, which is 10,000 times, the input 1mW , output 10W
Input power 1-5mW
Output Impedance: 50 Ohm, according to need adjustment between 10-200 Euro
Suite size: 60 x 100mm
Input 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
