Re: heat sink
The impedance of a capacitor is 1/(2*pi*freq*C)toggle quoted messageShow quoted text
At 30mhz, a 100pf capacitor will have an impedance of 1/(2*3..14*30e6*100e-12) = 53 ohms.
The output transformer at the IRF510 drain has a 1 to 4 impedance ratio, so the drains see an impedance of 50/4 = 12.5 ohms.
So you could have significant capacitance at the drain before it loads down a 30mhz signal by very much.
