I am interested in using an altered version of the S-A-A-2 PC board design/artwork, with an alteration to delete the built in bridge, and instead provide source output, reference input, reflect input and through input connections as four SMA connectors.
The purpose of this would be to permit other types of test sets (similar in concept to the HP/Agilent "option 011" - delete test set.) The benefit of this kind of interface is to allow additional test configurations that cannot be well supported currently due to damage limits in the bridge circuit (such as RF/microwave power amplifiers).
Before I expend additional time in this direction, I'm concerned about sourcing component parts (in US, probably from US distributors) for the PC board - are there any parts (other than the bridge-related circuitry which would be omitted) that I should focus on to avoid a show-stopper problem?
Thank you,
Dave
