RF Split Test Box For S11/S21

This is an RF testing box for s11/s21 and other miscellaneous test. It is broke down into 2 equal sides, A and B. All connections on that lettered side are tied together; with the banana jacks being also tied to their side. The grounds are even independent (most hobbyist use the same equipment for both side or have their equipment not on full isolation from each other [including the earth reference]; in that case you might find it more useful to bridge the ground terminal A and B in a semi-permanent fashion). I use this to test and build chokes and filters with this that are not yet in a case or other housing that would have easy to connect points. A lot of them will still have lead wires for development. This allows me to connect my equipment such as tracking generators and spectrum analyzers and or sources and load with the device under test making the bridge. This is intended for low power, 0dbm or less and obviously 50 ohm. I have not and would not recommend high power, as this is
