Ferrite core size and number of turns for transformer design

[sadehsatari]

hello.
I'm designing a 100w 4Mhz class E amplifier. I need a ferrite core transformer for impedance transformation and load isolation but unfortunately I lack the knowledge required for designing it. if anyone could guide me to a good book or a web page, or simply give me some formulas I would be very grateful.

thank you.

A Transmission Line Transformer is worth considering.
