AD9361 ad-fmcomms3_rev1 TX1A Output Port Question

I was looking at the evaluation board schematic (ad-fmcomms3_rev1.pdf) for the
AD9361 and I do not understand the TX1A_B (J212) schematic where a 2400-2500
MHz filter/amplifier path are combined together with C236 and C237 for a
non-filtered path. Can you please explain to me how this would work? Is this
meant to be a filter/gain path option and also an unamplified path combined
without a power combiner or use of an RF SPDT switch. Would appreciate the
insight as I am trying to learn what is being done here for my application of
this AD9361 IC. Thank you.
