All rights reserved Page 5 of 7 www.rakonxpress.com ESD Protection This product is electrostatic sensitive device. When you install or measure it, you should be careful not to add antistatic electricity or high voltage. Please be advised that you had better check anti serge voltage. To reduce the probability of damages caused by ESD, the following matching topologies should be applied. MLC varistor + ESD matching Suppressor diode + ESD matching ESD matching” should be added to the filter port, where electrostatic discharge is expected. It predominantly appears at the antenna input of RF receivers. Therefore “ESD matching” should be designed to short circuit or block the ESD pulse. Depending on the input impedance of the SAW filter and the source impedance, the needed component values have to be determined from case to case. In cases where ESD is minor, the following simplified “ESD matching” topologies can be used: Effectiveness of the applied ESD protection has to be checked according to relevant industry standards or customer specific requirements.
