I'm using some solid state relays, and having some problems with (I believe) EMI.I'm using this part in the B and C configurations.
These items are located near some RF sources operating at about148MHz. During transmit (.5W power), I'm getting some false "on" states. I'm pretty sure this isn't due to the equipment on the load side, as removal of the SSR's eliminates the effect.
- Anyone know if these type of SSRs are subject to EMI that can cause false on-states?
- Would induced AC voltages (from the RF source) in the load lines (around 148MHZ) decrease the R-off resistance?
- If the problem is in the SSR's, anyone have any suggestions regarding how to lessen/prevent this? (EMI shielding, other PN's that are immune to this, inductors/caps that could be placed in the load lines, etc).
Thanks for your time! Dave Harper
