I am interfacing a GSM antenna with some circuitry and need advice on the ESD device selection. Please guide me what should be the power handling capacity of the ESD device (as in power dissipation level). The GSM module I am using has an output power level of 2W.
Thanks for the reply. I am from Pakistan where the GSM frequencies are in all four bands (850,900, 1800, 1900 MHz). However, I am concerned about the power level of these pulses. I need to know what should be the power rating of the ESD protection device that we should use.
We are targeting IEC61000-4-2 for ESD protection. The contact discharge is +-8KV and air discharge is +-15KV. However, we need to know what should be the "power" level of the device selected for ESD protection.
What device will be destroyed by ESD on your phoneboard?
Nowdays,the front-end module in GSM phone,such as PAMs are all integrated ESD protection circuits which could pass the +/-8KV or +/-15kV ESD test. Additional ESD protection circuit will add your cost.
