Not wanting to use this with a transceiver, mostly just for my 70cm QFH with SDR for satnogs. Aware of any other 70cm and 2m LNAs that perform well for receive-only?
Hello Kevin,
I've heard good things about LNA4ALL (https://lna4all.blogspot.com/), which has a high IIP3 and low NF.
The +33dBm IIP3 would help with overload issues on the LNA itself, but the high gain (+23dB) would then overload your SDR/rig with those, now amplified, high-power out-of-band signals.
If you added an appropriate filter, such as the one I used, to the output, then you'd have a good solution.
