GSM Antenna ESD protection power level

Hi All,

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 in advance

Europe Standard: Contact +-8KV,
China CMCC: Contact +-10KV
Your country standard: ?

Hi,

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.

Thanks in advance,

Hi,

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.

Thanks in advance,

yours is the same as the Europe standards.
what do you mean the power level?

The attachment shows waveforms and component values for these tests from which you can calculate power.

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.
