Application information

7.1 Insertion loss

The IP425x family is mainly designed as EMI/RFI filters for multi-channel interfaces. The

measured insertion loss in a 50

Ω system for IP4251, IP4253 and IP4254 and the

simulated insertion loss for IP4252 is depicted in Figure 2.

The insertion loss was measured using the test set-up as depicted in Figure 1.
