TECHNICAL INFORMATION

FREQUENCY BEHAVIOR

The EMIF02-600FU7 is firstly designed as an EMI/RFI

filter. This low-pass filter is characterized by the following

parameters:

- Cut-off frequency

- Insertion loss

- High frequency rejection

Figure A1 gives these parameters, in particular the signal rejection at the GSM frequency is about -20dBm at 900MHz,

while the attenuation for FM broadcast range (around 100MHz) is better than -32dBm
