[Hackrf-dev] RF path: replacing MAX5864 with MAX5865

[Frank Liu]

Thanks for the quick reply! For the MAX2837, we were actually thinking of
just disabling the baseband filter via the LPF register. We'll be operating
in transmit mode for most of the time anyway, and we can apply digital
filters to any received signals we need to clean up.
