Post Troubleshooting: 5V rail droop when powering MiniCircuits components

Hi there!

When I add power to the MiniCircuits components, my 5V rail droops down to about 3V. The 12V rail is still fine. When I take an ohmmeter to the power terminals of the RF chain, I get a resistance of ~.38k. The resistance across the 5V rail on the breadboard is ~.7k without the RF chain connected. I haven't worked with MiniCircuits components much, so I'm a bit stymied as to where to look next... any tips?
