Satellite Communications/Output power from BUC
I have 5 watt BUC & i need to know the exact gain of it & the relation between the i/p power & the o/p ?
The small signal gain is something that can be found on the datasheets.
The actual gain will also depend on the attenuation that is set (if possible) on the input signal.
Alternatively, you could make a plot of input power versus output power.
In that case, connecte the BUC to a dummy load and insert a directional coupler between BUC and load to measure the output power.
I hope this helps,
