Hello all,
Quick question about power combiners using: wilkinson, branch line, and rate race. We are working at power levels of 30-35dBm, and I was worried about the power ratings for the resistors in those types of power combiners.
For the branch line and rate race, assuming a pretty decent match to the coupler, the resistor should be isolated and burn no power, right?
However, I dont remember much about a wilkinson. The flash backs to a virtual short under odd mode, make me think the resistor might see some appreciable current?
Any clarification would be much appreciated!
Thanks in advance,
Sami
