We are considering using a tuned stub filter to suppress the carrier so that we do not overload our spectrum analyzer while measuring spurious emissions. One question we have concerns the Q of the filter - i.e., will it sufficiently suppress the modulation sidebands. So, let me ask the following questions. In the frequency ranges of 860-1000 MHz and 2.45 GHz, how much suppression should I expect from a stub filter and what design steps can be taken to have the necessary bandwidth? Or, am I going down the wrong path for a filter?
