434mhz Preamp + Filter

I’ve designed a prototype antenna preamp with SAW filter for my HAB tracker setup.

The board is including a voltage regulator and supporting power over coaxial or external battery options.
Preamp gain is ~20db  and SAW filter is eliminating out of the band with a small cost(-3db).

The results are promising. So, We will design and manufacture SAW filtered version for HAB and non-SAW versions for FPV setups.
They will be in stocks in a few weeks on Flytron.com
