I think, the middle path is the 5.8GHz-CE version - as you suggested without power amp. Thus I believe, the left path is the 2.4GHz CE subcircuit. It would be interesting to know, what the black 8-pin IC in the upper left corner of the photo is. May be a 2.4G power amp including switch or a...

I would be interesting to measure the integrated logarithmic power detector output level of the SKY 85748-11 (Pin5) in a MM FCC version while operating in USA and compare it to the output level of a MM FCC version while operating in Europe or another CE-country. In CE-countries, it should be...

Based on Blithe74’s photos, it seems, there are three paths from the Atheros WIFI controller to the antennas: 1: 2.4 GHz at CE power level (using the Atheros internal RF power amplifier?) 2: 5.8 GHz at CE power level (using the Atheros internal RF power amplifier?) 3: 5.8 GHz at FCC power...

I found the full datasheet with application circuit diagram and evaluation board of the SKY 85748-11 5GHz front end IC: https://www.richardsonrfpd.com/docs/rfpd/SKY85748-11.pdf
