It appears to be grossly over-engineered as well, an ASIC feeds one
each amplifier separately and the amps appear to run at very low
power. No doubt a much cheaper transmitter could be made, this one is
also physically large as well!

Far more things than you can imagine are designed like this. On short runs
it isn't cost effective to come up with an efficient design. Same applies to
a lot of software!
