Reflectionless Filter Application Note

An application circuit was assembled to measure the IF reflection

spectrum at the output of a mixer when the mixer was paired with a

conventional filter versus a reflectionless filter.

While the conventional filter reduces the reflections present when

the mixer is used alone (no filter), the reflectionless filter virtually

eliminates those reflections altogether.

The reflected signal at marker 1 in the figures above exhibits a

reduction of more than 20 dB from -28.7 dBm to -50.3 dBm when

the reflectionless filter is used as compared to the conventional filter,

thus eliminating unwanted spurious mixing products and improving-

system dynamic range.
