Hi,
I need to design a circuit that will provide power to a TV antenna amplifier.
My constraints are :
* Characteristic impedance : 75 Ohm,
* Power supply for antenna amplifier : 24V @ 100mA and
* Available power supply : 9V @ 1.6A
I think I will base the solution on a step-up converter.
But I have a concern about the harmonics of the switching frequency.
Moreover, I do not know how to calculate the inductor and the capacitor (not the one of the step-up convert but the capacitor which blocks DC to TV and the inductor which blocks HF to the step-up converter).
Thanks in advance
