Yes, two different versions;
cf1090-kt30-wide 1090 MHz cavity filter for Mode-S / ADS-B - wideband
cf1090-kt30 1090 MHz cavity filter for Mode-S / ADS-B
Both work excellent esp the outer band behaviour.
I still have to hook them up to a NanoVNA that I ordered, but it seems to take like forever to arrive here. I’d like to experiment with the effect of a low and high temperature environment (put 'em in the freezer/oven for a while).
Another advantage is that they are DC shorted so no static build-up.
I want to place it in a box with a Triple Filter LNA (the MGA-13116 has better Noise and Linearity figures than the PSA4-5043+)
