High isolation A to B switch, need for some applications such as extension of the antenna matrix.
The most common use case is routing the antenna between two existing antenna switches. For these cases it doesn’t need to have as high isolation as the RS3000 or 1A2R due to the high isolation the switches it’s connected to.
Additional isolation is realized by grounding of the unused port.
It has an LED to indicate “out B” status. When powered off the input is routed to out A.
AB switch is powered by 13-15V through a dedicated power connector.
