Christian,
Excellent? overview "H mode" mixers, thanks!
I am considering the ADL5801, seems to be a good active mixer, a bit more noise compared to a passive mixer.
The main reason I am looking to an active mixer is not having to design a diplexer between the first mixer and the 2.5GHz cavity filter.
In the current setup without a diplexer the performance of the passive mixer I tried (SIM-83+) is not as expected.
I tried with 10dB attenuators between LO and LO port or between mixer output and cavity filter and with a buffer amplifier between mixer and cavity filter but that did not make a big difference, maybe something else is wrong?
