Avago Technologies has announced two advanced film bulk acoustic resonator (FBAR) technology-based bandpass filters for 4G WiMAX/LTE handsets, data cards and access points. The ACPF-7024 and ACPF-7025 are a pair of highly selective bandpass filters that enable products to offer simultaneous operation of voice communications and WiFi/Bluetooth data networks without compromising either voice or data quality of service. The ACPF-7024 is a 2400-2482 MHz WiFi/Bluetooth bandpass filter designed for use in the 2,4 GHz ISM1 band and features over 40 dB of attenuation to interfering signals. The ACPF-7025 is a miniature 2496–2690 MHz WiMAX bandpass filter combined with a WLAN/WiFi band-reject filter. Cell band rejection is 60 dB typical; PCS band rejection is 43 dB typical; and WiFi/WLAN/Bluetooth rejection is 43 dB typical.
