5.0 out of 5 stars Well designed filter
Reviewed in Canada 🇨🇦 on January 9, 2018
This is an excellent filter. I have attached it to my Rigol DSA815 tracking analyzer and measured the insertion loss around -2dB, pass bandwidth around 220MHz and band rejection at -45dB. The insertion loss is likely a little less because of the number of adapters I had to use to attach it to the analyzer (easily 1dB, I estimate). Using this filter in an ADSB receiver setup using an SDR will reduce the noise floor significantly allowing you to increase the SDR gain and improve SNR.
