Dear Sir/ Madam,
when I use ADG904, should i need connecnt another 50ohm resistor on the reciver board. And whether or not the ADG904 could operate bidirection.
No there is no need to 50ohm resistor on the receiver board but all you need to make sure that the trace or the pin its connecting on the receiver board is 50ohm as its RF trace.
ADG904 can be used as bidirectional switch.
