AUDIO-1-KIT combines TDK InvenSense MEMS microphones with TDK
brand’s noise suppression filters (MAF series) and ESD notch filters
(AVRF series) specifically designed to combat typical issues in audio lines,
while offering additional benefits such as improving reception sensitivity in
cellular or Wi-Fi communication.
Figure 1 shows an example of noise
countermeasures in microphone lines using MAF
series noise suppression filters and AVRF series
ESD Notch Filters, and their effectiveness. It can
be clearly seen that in filter circuits that use both
MAF and AVRF series products together, the
insertion loss in cellular bands is even larger than
in circuits that use only MAF products.
