SAN JOSE, USA & SINGAPORE: Avago Technologies has announced two advanced Film Bulk Acoustic Resonator (FBAR) technology-based bandpass filters for next generation 4G WiMAX/LTE handsets, data cards and access points.
The Avago ACPF-7024 and ACPF-7025 are a pair of highly selective bandpass filters that enable cellular phones to offer simultaneous operation of next generation 4G WiMAX/LTE voice communications and WiFi/Bluetooth data networks without compromising either voice or data quality of service.
The ACPF-7024 solves the design problem of enabling concurrent operation of WiFi and/or Bluetooth standards with other wireless standards - such as 2.5 GHz WiMAX, PCS, and LTE Bands 7 and 40 - without performance degradation due to adjacent radio interference. 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.
Avago’s ACPF-7025 is a miniature 2496 - 2690 MHz WiMAX bandpass filter. The ACPF-7025 allows a WiMAX transceiver to coexist and operate alongside WiFi and/or Bluetooth transmitters. Cell band rejection is 60 dB typical; PCS band rejection is 43 dB typical; and WiFi/WLAN/Bluetooth rejection is 43 dB typical.
Both the ACPF-7024 and ACPF-7025 use Avago Technologies’ proprietary Film Bulk Acoustic Resonator (FBAR) technology that makes ultra-small, high-Q filters possible at a fraction of their usual size. By utilizing Avago’s advanced Microcap bonded-wafer chip-scale packaging and proprietary FBAR filter technologies, the ACPF-7024 and ACPF-7025 are assembled into molded chip-on-board modules with a compact size of 2.5 x 2.5 mm and 2.0 x 1.6 mm respectively.
Applications for the ACPF-7024 and ACPF-7025 include 4G/LTE cellular and 802.11 b/g/n WiLAN/WiFi and Bluetooth data communications in handsets and portable communication devices such as laptops, netbooks and tablet devices.
