5.4 EMC and ESD Notes

EMC tests should be performed to detect any potential problems. Possible harmful emissions radiate by

the application to the RF receiver in the receiver band. RF emissions interfere with audio input/output. It is

recommended to shield the sensitive components and trace with common ground and user can add beads

where necessary.

Normally SIM5320A is mounted on customer host board. Although some ESD components have been

added in SIM5320A, to prevent ESD, user should put some ESD components on customers’ board. The

ESD components should be placed beside the connectors which human body might touch, such as SIM

card holder, audio jacks, switches, keys, etc. The following table is the SIM5320A ESD measurement

performance; the results are from SIMCom EVB test.
