frequencies of 800-900 MHz and
1.9GHz as well as the growing
wireless LAN frequencies of 2.4-
6GHz can couple into the audio port
of a handheld device and adversely
affect its performance. FCC Part 15
sets maximum allowable emission and
immunity levels for all digital devices.
IMPORTANT: For the most current data, consult MICROSEMI’s website:
S Filter response characterized up to 6 GHz
S Low insertion loss in the pass band
S >20dB attenuation in the 800-900 MHz range
S >15dB attenuation in the WLAN frequencies of 2.4GHz and 5.0-6.0 GHz
