2SC1971 8 Watts FM broadcast (87,5-108MHz) broadband microstripline RF-amplifier

1.- all SMD components are 1206 types
2.- connect the bottomlayer (groundplane) on several points (through via's) with the 
    toplayer of the pcb. THIS IS VERY IMPORTANT!


VCC = Supply voltage (see also the 2SC1971 datasheet)

CuL = magnetwire, enameled copper wire
(Note:	  1 mm equals approx. to #18 A.W.G
	0.8 mm equals approx. to #20 A.W.G
	0,3 mm equals approx. to #28 A.W.G.)

(I)   all diameters are measured from the inside of the coils, i.e. 'internal' diameter.
(II)  make sure to mount the rf-transistor on a appropriate heatsink and use some thermal
      heatsink compound between the flange of the transistor and heatsink!
      (Thermal resistance heatsink at least 6°C/W.)
(III) all parts are soldered directly on the toplayer of the pcb.
