I was mainly waiting on the 0.1% 0603 resistors to show up from DigiKey and the weekend to actually work on it. After all was said and done, I ended up with a compact single piece unit to keep track of instead of 5 little pieces.
Back to the junk drawer for the edge launch female SMAs and 0.062" board. It all went together fairly well but did have to use the drill press, Dremel tool, hand knife, nibbler, and an awl to carve out the board near the loads. The short was a round piece of copper with a hole drilled in the center and soldered down to the connector.
After calibrating my AA-600 to some know good OSL standards I checked it against this little fixture and all seemed okay. The 50-Ω load was 2 parallel 100-Ω loads and it turned out better than I expected. The 200-Ω load is a single 200-Ω load and the 100-Ω load is a parallel combination of 2-100 Ω 0.1% 0603s. The 50-Ω termination measured at least 45dB return loss at the highest frequency of 230MHz. Agilent's (or Keysight rather) threshold for CAL loads is 42dB return loss. Check.
