Note: This HF LNA design is inspired by Charlie Morris ZL2CTM's prior work.

The idea that a single-transistor-preamp with 10 dB gain is more than enough for HF comes from Gajendra Kumar (VU2BGS). As a new "designer" I am often overwhelmed by the different possible design paths - so having guidance from an elmer becomes crucial.

HF LNA 1

HF LNA 2

It seems even MMBT2222A should work for building a HF LNA!

HF LNA 3

This LNA will be used in the RX path of the DDX Commercial series of transceivers soon!
