Hi Gurus,
I am confused at the power delivered to load. When the load is 50ohm//100Mohm, equivalently the load is 50ohm, then in my opinion with Psource = 20dBm (6.3Vpp), voltage swing at the load should be 6.3Vpp as well. But in Spectre simulation, the voltage swing at the load is 12.6Vpp, that is exactly the power level at the load when the load is an open(100M). But the load is actually a 50ohm//100Mohm? Why the load can't be seen as 50ohm?
Kind regards,
RF design beginner
