VOLTAGE 13.8V - 15V
The layout of the 2SC1946 28 Watts FM broadcast RF amplifier has been created with sPRINT Layout v3.0. You can get a Shareware copy at: http://www.abacom.de. The pcb outline is 100 x 50 mm (width x height).
RF Amplifier Parts List
All component values are drawn on the .comp and .silklayer bitmaps, with the following exception(s);
all four (4) coils (in the lowpass filter section) are: 3.5 turns, 8 mm DIA., 1.2 mm CuL closewound i.e. no wirespacing.
CuL = magnetwire, enameled copper wire, insulated (rigid) copper wire e.t.c..
2 mm equals approx. to #12 A.W.G
1 mm equals approx. to #18 A.W.G
1.2 mm equals approx. to #17 A.W.G
0.8 mm equals approx. to #20 A.W.G
0.3 mm equals approx. to #28 A.W.G.)
All diameters are measured from the inside of the coils, i.e. ‘internal’ diameter.
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.)
