There are a few things to consider. First, try only entering your DC Supply, the min application frequency, and the max application frequency. If you get results, then you can sort the results table to see which product best meets your other criteria, and then refine your search.
If you still do not get results, then consider narrowing up your frequency band. We assume you want a single RF tuning match, so we take into account fractional bandwidth. Some of our amplifiers can be tuned with a single match to cover a very large fractional bandwidth, but others are more narrow band.
If you still don't get results, try a different DC Supply. Perhaps we don't have an amplifier that covers your frequency band at the DC Supply you are requesting.
