1. A method of processing a signal using radio frequency circuitry, the method comprising:
by a logic board having a first remote head at a first end and a second remote head at a second end separated from the first end:
outputting a first analog electrical signal indicative of first data to be wirelessly transmitted through the first remote head and selectively over a first antenna or a second antenna of the first remote head and transmitted through the first remote head via a first electrical connector;
amplifying, using a first power amplifier of the first remote head, the first analog electrical signal using a first antenna integrated circuit of the first remote head to generate a first amplified analog electrical signal, wherein the first antenna integrated circuit is communicatively coupled to the first antenna and the second antenna;
outputting a second analog electrical signal indicative of second data to be wirelessly transmitted through the second remote head and selectively over a third antenna or a fourth antenna of the second remote head and transmitted through the second remote head via a second electrical connector; and
amplifying, using a second power amplifier of the second remote head, the second analog electrical signal using a second antenna integrated circuit of the second remote head to generate a second amplified analog electrical signal, wherein the second antenna integrated circuit is communicatively coupled to the third antenna and the fourth antenna.
