PEMIxQFN; PEMI2STD family

1-, 2-, 4-, 6- and 8-channel passive filter network with ESD protection

All important values of the RF behavior such as relative

3dB frequency, insertion loss at

800 MHz and above and also the DC attenuation in an NWA environment can be derived

from the insertion loss response curves depicted in Figure 2 to 6.

Note: insertion loss at low frequencies (1 MHz) is nearly independent from the channel

capacitance values available within the PEMI family.
