RF amplifier with BLY90

• RF amplifier with BLY90

  • project of circuit potency lineal RF amplifier with BLY90 for Fm transmitter or vhf transmitter
    
    Circuit for lineal amplifier for VHF with power source and printed circuit board, using the transistor Bly90
      It is to be used as amplifier of potency of RF in the high strip of of the power source that should be capable to supply a tension of 13 volts with a current of 10 amperes. it demands right care in the assembly of the source. Terrified armored transformer, and three shocks of RF to filter the components of high frequency.
     XRF1 and XRF2 are 30 you turns of wire 25 AWG in a nucleus of ferrite of 1 cm of diameter and 5 cm length. It can use one of a source at/atx bad, it is easier. XRF3 are 100 you turns of wire 25 AWG in a ferrite nucleus and 1cm of diameter for 5cm of length. Or use an usually found in the exits of sources ATX’s. something around 100µH. The capacitors C1, C2, C3, C4 should be ceramic of 600 V or more and the capacitors of 10nF are for 100v. RX cannot be of wire.
