I'm pretty happy with the top side Samtec ARF6 launch simulations now.
S11:
* Red: No cutout, -12 dB at 10 GHz, -7 at 20 GHz, -4.8 at 30 GHz
* Blue: Rectangular ground cutout the size of the pad, -22.5 at 10 GHz, -16.4 at 20 GHz, -11.7 at 30 GHz
* Green: 30um larger than the pad on all sides (1.06 x 0.41 mm), -30.5 at 10 GHz, -22 at 20, -15 at 30.
With the oversized cutout it's more than good enough for QSGMII and 25Gbase-R.
TDR:

A screenshot of my full post (available in the link of this post). It reads (in part): "In this reading note, Mandy quotes from Verlyn Klinkenborg’s: "...why not give up on the idea of “flow” and accept the basic truth about writing? It’s hard work, and it’s been hard work for everyone all along. There’s good reason to believe this, apart from the fact that it’s true.
