DIY 45W SSB HF Linear Power Amplifier Amateur Radio Transceiver Shortwave Radio Development Board KitNote: 2sc1971 has long been Stop production, so this version uses disassemble parts, please note that before you buy it.
Manual: >>>>><<<<<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 1-5mW
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 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 unsafeIn 3-5MHz, due to the low frequency, low inductance, resulting in a gain of a certain loss of output power a little lower than 7MHz3.500MHz 54W
Package included:1 x DIY 45W SSB HF Linear Power Amplifier Amateur Radio Transceiver Shortwave Radio Development Board Kit
