Nooelec SAWBird LNA checked on NanoVNA with 40dB attenuation at LRO 6/3/2025

As 40dB attenuation in the circuit, then need to add 40dB to reading on VNA. Once this is done, it is clear that the SAWBird produces roughly 40dB of amplification = S21 Logmag 10dB = 0.15dB ==> amplification = 0.15dB+40dB = 40.15dB.
