[Hackrf-dev] Replacing the LNA/PA

[Chuck McManis]

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.
