If my memory serves me correctly the major difference between the ne and se
version had to do with the temperature range they were spec'd over.

Enlarging the photo of the backside of the housing, it shows HW version
4.4_ZK
I found at the page descrition why HW
version 4.4_ZK is released:
"The latest version is NanoVNA-H rev3.6 and NanoVNA-H4 rev4.3. NXP has
discontinued the dual balanced mixers SA602A/SA612A/NE602A/NE612A in
November 2022,
Hugen is using ZeenKo NE602A to replace the SA602A/SA612A starting with
the NanoVNA-H v3.7 and NanoVNA-H4 v4.4 versions,
and that the version also improves the dynamics when using the base wave.
I am curious what the improvement of the dynamics
entails.Doesanyonehaveexperiencewiththis?
