I used Wilkinson 2-way splitter/combiner to combine PA power. The frequency is 900MHz. The port 2 power is 20W, and port 3 is also 20W, so port 1 is 40W. Normaly, the balance resistor (100Ω) is lossless and can provide good isolation between port 2 and port 3. But how to choose the power rating for the balance resistor? And how to compute the power consumed by resistor for mismatch? Please help me. Thanks.
