Analysing spare Nooelec SAWBird H1 LNAs at LRO 6 March 2025 using NanoVNA (Vector Network Analyser)

Admin March 6, 2025 No Comments

I used a NanoVNA vector network analyser to analyse my spare Nooelec SAWBIrd H1 low noise amplifiers. In each case, the level is around 0dB – so, when 40dB attenuation…

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

Admin March 6, 2025 No Comments

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…
