As Wi-Fi and wireless IoT technology spreads throughout multiple industries, including automotive, communications, industrial, and healthcare markets, a number of challenges arise concerning the large numbers of nodes and their eventual competition for bandwidth and signal integrity.
Key challenges to Wi-Fi and IoT systems include, sensitivity. minimizing front-end losses, harmonic interference, other “service” interference (e.g. cell phone, 5G, LTE).
Acoustic wave (SAW) filters and bulk acoustic wave (BAW) filters provide a filtering function for RF signals at defined frequencies. By using SAW and BAW filters, interferers can be suppressed, and the sensitivity and reliability of receivers can be enhanced.
