Maybe you could slightly improve noise figure with a better amp, but prolly not worth the trouble. ___ HackRF-dev mailing list HackRF-dev@greatscottgadgets.com https://pairlist9.pair.net/mailman/listinfo/hackrf-dev
Re: [Hackrf-dev] Replacing the LNA/PA
Robert, are you looking to fix a broken HackRF or are you re-designing it to eliminate the use of an obsolete part? If its the former, the part is still available and if history is any guide it will continue to be available in piece parts and lots of various sizes for several years. --Chuck On Sat, Feb 17, 2018 at 10:18 PM, Robert Chadwick via HackRF-dev < hackrf-dev@greatscottgadgets.com> wrote: > Sorry if this is a duplicate. > > Looking at the schematic, it appears the HackRF uses a MGA-81563 for the > LNA and PA.

[Hackrf-dev] Replacing the LNA/PA
Sorry if this is a duplicate. Looking at the schematic, it appears the HackRF uses a MGA-81563 for the LNA and PA. As these appear to be EOL, and there appear to be many complaints about the RX performance of the HackRF, has anyone replaced these with something better? While I haven't yet looked closely at datasheets to check compatibility and pinout, looking through Digikey there appears to be a number of possibilities. Might it be possible to fit in a PSA4-5043+ in place of the MGA-81563? ___ HackRF-dev mailing list HackRF-dev@greatscottgadgets.com https://pairlist9.pair.net/mailman/listinfo/hackrf-dev
