I made a little box for the new RF amplifiers we'll be using for the green beatnotes, to keep things tidy on the PSL table. They are both Minicircuits model ZHL-3A-S.

I took TFs of their response with the agilient analyzer (calibrating out the cables, splitters, etc.) Powered at +24V, we get a solid ~27dB of gain up to around 200MHz, which is fine for our needs. The phase profile is mostly a 6-7 nsec delay, which is negligible for ALS. Data files are attached. 

Koji looked at me like I was crazy for using a BNC connector for the DC power. I haven't yet been able to find panel mount banana connectors, but when I do, I'll replace it.
