Rf 150W BlX15 power amplifier
Rf 150W Blx15 power amplifier, enough to cover 50Km with one folded dipole.
You must use one heatsink about 20 cm wide, 5 cm height and minimum one cooler.
Components:
* L1 = 2 turns / 9mm / 1mm
* L2 = L5 = rf choke 1mH
* L3 = 3 turns / 9mm / 1.5mm
* L4 = wide - 7mm / length - 40mm
* L6 = 3 turns / 7mm / 1.5mm
* L7 = 4 turns / 7mm / 1.5mm
Please take good care when you adjust this 150W amplifier because you can get some serious injures. BLX15 works at 50V contionous current and sometimes this can be fatal.
BLX15 has a SOT-55 case and the following characteristics:
ssb; class AB / Vce = 50V / Freq(MHz) = 1.6 … 28MHz / Output(W) = 20…150W / Power Gain = 14 dB
ssb; class A / Vce = 40V / Freq(MHz) = 1.6 … 28MHz / Output(W) = 30W / Power Gain = 14 dB
cw; class B / Vce = 50V / Freq(MHz) = 70MHz / Output(W) = 150W / Power Gain = 10 dB
cw; class B / Vce = 50V / Freq(MHz) = 108MHz / Output(W) = 150W / Power Gain = 7.4 dB
