IP3 calculator
IP3 calculator - calculates either IM3, P_out or IP3, given the other two parameters. Voltages are referenced to 50 Ohms. If output power is combined power of 2 tones, then IM3 is also combined (left+right) power. If output power is per tone, then IM3 is also per tone. Both sides are assumed to be equal, if not, then use total powers (Pout total and IM3 total).
Leave the field which needs to be computed empty (after a computation, if all fields are non-empty then previous field will be computed).
