I'm using the RF bridge to combine 2 signal source for TOI measurement. Anyhow, would like to know is there any others alternative way to combine 2 signal source with a good isolate btw 2 port. Need help !!!
For TOI measurement, to combine 2 signal source, we have a lot of choices (Rf bridge, directional coupler) but most important is the accuracy for the measurement. I think the key spec to be consider are:
Key spec to be consider:
- coupling factor
- transmission loss
- input power
My concern is will this spec have a lot of influence at low freq such as 100 kHz - 300 kHz? What if we don't have good isolation from 100kHz - 300 kHz?
