I recently decided to conceive a 10W class 446MHz amplifier.
I want to be able to amplify a 100mW signal into a 10W, for that i'm going for a two stages amplifier :
- SKY65162 to amplify the signal to 1W
- Then a 2SK3075 to reach 10W approx.
The first amplifier is very well documented in the datasheet, but the second is more tricky. I have this datasheet which describes partly the circuit to make use of the transistor :
This schematic is supposed to describes the circuit required to function at around 500MHz. I was going to use theses values but I thought i could use some help and some tips from you.
What length shall be the transmission lines made like resistor on the schematic ?
Thanks for your help
