Which is cheaper -- a amplifier that is forward-only, or one that incorporates Rx/Tx handoff?
There are numerous reasons appart from outright cost of outboard bidirectional gear. One may wish to have Tx-only and Rx-only paths. Say you wanted to really push the SIFS timer -- saving a few microseconds here and there is important.
Also, generaly speaking, forward-only amplifiers will exhibit reduced self-noise and less group delay accross the effective band.
