HackRF Frontend/BaseBand
RF Frontend BaseBand / IF (Intermediate Freq)
RF Frontend: Generic term for all the
circuitry between the antenna and the
first intermediate frequency (IF) stage
http://en.wikipedia.org/wiki/RF_front_end
Baseband refers to the original frequency
range of a transmission signal before it is
converted, or modulated, to a different
frequency range
