[Amps] L section of Pi-L filter

[Ulf Tjerneld]

Hi,

Question 1: I'm considering using toroids in the L-section of my RF tank. Are there any guidelines regarding suitable cores, wires and turns?

Question 2: If I stay with a traditional air wound coil for the L-section what would be a suitable wire diameter for a 1 KW amp? I'm pretty sure it does not have to be the same heavy gauge as in the Pi-section!

Thanks for any answer!
