IP4337CX18/LF

7-channel integrated filter network with ESD input protection

7.2 Crosstalk

The crosstalk measurement configuration of a typical 50

Ω NWA system for evaluation of

the IP4337CX18/LF is shown in Figure 5.

The measured crosstalk within the IP4337CX18/LF in a 50

Ω NWA system from one

channel to another is shown in Figure 6 for four different pairs of channels. In all cases,

unused connections are terminated with 50

Ω to ground.
