RF Switch in non supported state
RF Switch in non supported state
(OP)
Hi, I want to use an RF Switch that has two control signals A,B and supports only two states (RFC to RF1 and RFC to RF2)according to the input voltages at A,B. What would happen if I put the same voltage at the two control lines(0 Volts at A and 0 Volts at B). I want the switch to be off! I haven't found a switch that has the unused states defined. But I need to have it off when I want to...
the switch is :

Thanks alot!

RE: RF Switch in non supported state
Modify your circuit to always ensure the chip's lines are in a valid state. If you need the switch off and the chip doesn't allow that state, you need to disable the inputs to the chip, plain and simple.

Might be applicable to your part. Contact Hittite to be sure.

HMC349 except that I want a lower power one (in order to keep the consumption of the circuit low).

Not the same. Which favor do you need?
