We offer 2 types of swept sma radius right angle adapters. For some of these adapters we sweep both the inner conductor & outer ground; these are sometimes referred to as "sma elbows". For other adapters we place a swept inner conductor inside a rectangular housing; so they're swept on the inside, square on the outside.
The 6ghz right angle sma adapters have an abrupt right angle internal construction; performance is actually well behaved to above 12ghz, but these sma right angle adapters do very well up to 6ghz.
The SMA T's or SMA Tee's are simply an abrupt right angle connection hence we only spec them to 6Ghz.
