Analysing spare Nooelec SAWBird H1 LNAs at LRO 6 March 2025 using NanoVNA (Vector Network Analyser)
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…
Procedure for using NanoVNA to test Nooelec SAWBird H1 LNA
Hi Andy, Sorry I’ve been driving all day so just seen this. I hope I’m not teaching you to suck eggs, but it seems from some of the posts that…
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…
Antistatic bags used to protect electronic components
Those are called anti-static bags or ESD (Electrostatic Discharge) bags. They are used to protect sensitive electronic components from static electricity damage during storage and transport. There are two main…
