      150 Watts BLF177 FM broadcast (87,5-108MHz) RF-broadband amplifier
      ================================================== ================
    
      The amplifier requires max. 8 Watts rf-drive to deliver 150 Watts output power.
      Supply voltage : 50 Volts, adjust bias to approx. 1,8 Volts.
    
    
      CuAg = silver plated copper wire
      CuL = magnetwire, enameled copper wire
      (Note: 1 mm CuL equals approx. to AWG18
      0,3 mm equals approx. to AWG28)
    
      (I) all diameters are measured from the inside of the coils
      (II) make sure to mount the rf-transistor on a appropriate heatsink and use some thermal
      heatsink compound between the stud of the rf-transistor and the heatsink!
      (Thermal resistance heatsink at least 6°C/W.)
      (III) all parts are soldered directly on the toplayer of the pcb
      (IV) connect the bottomlayer to the groundplane on the toplayer!
