IP4365CX11

Integrated SIM card passive filter array and USB ESD protection

7.2 Insertion loss

The IP4365CX11 is mainly designed as an EMI/RFI filter for SIM card interfaces.

The insertion loss measurement configuration of a typical 50

Ω NetWork Analyzer (NWA)

system for evaluation of the IP4365CX11 is shown in Figure 4.

The insertion loss in a 50

Ω NWA system for all three resistor equipped channels of

IP4365CX11 is depicted in Figure 5. The insertion loss is measured with a test

Printed-Circuit Board (PCB) utilizing laser drilled micro-via holes that connect the PCB

ground plane to the ground pins.
