DIY 45W SSB HF Linear Power Amplifier Amateur Radio Transceiver Shortwave Radio Development Board Kit

DIY 45W SSB HF Linear Power Amplifier Amateur Radio Transceiver Shortwave Radio Development Board Kit Note: 2sc1971 has long been Stop production, so this version uses disassemble parts, please note that before you buy it. Manual: >>>>>Here<<<<< 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
