According to the HMC545AE HF-Switch datasheet the logic outputs A and B switch the HF signal from pin 5 (RFC) to RF2 or RF1.
However, if I use a similar test layout as in the Eval-kit I am seeing the input signal an BOTH outputs (RF1 and RF2) regardless of control signals.
I am using A=+5V and B=0V as control signals.
I bought the parts via Mouser and I triple checked the pin assignment / datasheet and so on.
How is this possible? I expect "RF1 and RF2 are reflective shorts when “Off” and no signal propagation on the side, that is OFF.
