Hi,
I am new in this forum so not sure where to post this question. Anyway, I have been trying to design a 13.5Mhz, 30Watt Class e amplifier. The class e amplifier seems to work very well according to the simulator, in the class e amplifier design I used two irf 520 in parallel.In simulator I have been driving these IRF520 using signal generator. In practice I intend to drive this mosfets using DEIC420.
In the datasheet of DEIC 420 there is a test circuit shown with all the bypass capacitors and resistances. According to this diagram 4 1/2 watt ferrite beads with a resistance of 7ohms are required in series with the power supply to the DEIC 420.
Now the questions are
1-the datasheet is little bit unclear to me whether the beads are 7ohms or 70 ohms?
2-In digikey ferrite beads are sold according to ampre rating;for example I have brought 7ohm 3amps ferrite beads.So far I have not seen any watt rating for the beads.So I am not sure if the beads are correct.
sorry for the long question.Please give me some advice if anyone here has any experience with DEIC420.
