HMC986A is a SPDT. The truth table mentioned the cases where the control voltage connects the common port to RF1 or RF2. Is it possible to connect it to nothing (all ports are open)?
HMC986A does not support all off state. V1=V2=high and V1=V2=low are undefined states and not shown in truth table. In these undefined states, RF1 and RF2 paths will be in have poor return loss and high insertion loss.
The s-parameters data on web page includes these undefined states.
