Q. How does the return loss at the output of a frequency doubler vary as input power changes? A. Return loss is influenced by how hard the diodes are driven in their conducting state. As input power to the frequency doubler is reduced, the impedance will increase. It...

Q. What is the difference between an absorptive and a reflective switch? A. In a reflective switch, the impedance of the port that is OFF will not be 50Ω and will have a very high VSWR. On the other hand, an absorptive switch will have a good VSWR on each port...

Q. How critical is LO level in a mixer application? A. The purpose of the LO signal is to switch the mixer diodes on and off. Mixer manufacturers select fixed LO levels so they can test and specify at each particular level. In practice, however, LO drive can vary with...
