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 SIM7100A is mounted on customer host board. Although some ESD components have been
added in SIM7100A, 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 SIM7100A ESD measurement
performance; the results are from SIMCom EVB test.
