    FM transmitter simulation

    One way to simulate (with ADS for example) FM transmitter is to make a transient simulation. The problem with this is the long time consumed. What is the correct way of doing this? Envelope, HB or what? I want to see how well my transmitter oscillator is working and also the output spectrum as...

    Voltage or power added

    Hi, I have a question about analyzing different coupler types. If you use a Wilkinson power combiner you add the power from the two input branches. That is clear so far. For a directional coupler it is different. Let's name the branches as: port 1 is the one you input the signal on. Port 2 is...
