Neil I think you are a little cautious about proper SMA connectors at the 100W level. I and quite a few others use ILAM amps for 13cm EME that run close to 250W through one, and the output microstrip hybrid for my 2x40W PA at 9cm uses them.
No issues with them failing yet.

See https://www.electronics-notes.com/articles/electronic_components/rf-connectors/sma-connector.php

Unlike my cheap Chinese directional coupler with N connectors on it that burned out at 300W on 23cm!
