DESCRIPTION
DIY 45W SSB HF Linear Power Amplifier Amateur Radio Transceiver Shortwave Radio Development Board Kit.
Description:
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.
working voltage and current: 12-15V,6-8A.
Output 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 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.
3.500MHz 54W;
7.050MHz 56W;
10.000MHz 57W;
14.270MHz 55W;
21.400MHz 41W;
24.000MHz 37W;
28.100MHz 25W;
29.600MHz 20W;
Package included:
1 x DIY 45W SSB HF Linear Power Amplifier Amateur Radio Transceiver Shortwave Radio Development Board Kit.
