Avago Technologies has launched 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 mobile phones to offer simultaneous operation of next-generation 4G Wimax/LTE voice communications and Wi-Fi/Bluetooth data networks without compromising voice or data quality of service.

The ACPF-7024 enables the concurrent operation of Wi-Fi and/or Bluetooth with other wireless standards – such as 2.5GHz Wimax, PCS and LTE Bands 7 and 40 – without performance degradation due to adjacent radio interference.

The ACPF-7024 is a 2,400-2,482MHz Wi-Fi/Bluetooth bandpass filter designed for use in the 2.4GHz ISM1 band and features over 40dB of attenuation to interfering signals.

Avago’s ACPF-7025 is a miniature 2,496-2,690MHz Wimax bandpass filter combined with a WLAN/Wi-Fi band-reject filter.

The ACPF-7025 allows a Wimax transceiver to coexist and operate alongside Wi-Fi and/or Bluetooth transmitters.

Cell band rejection is 60dB typical; PCS band rejection is 43dB typical; and Wi-Fi/WLAN/Bluetooth rejection is 43dB typical.

Both the ACPF-7024 and ACPF-7025 use Avago’s proprietary Film Bulk Acoustic Resonator (FBAR) technology that makes ultra-small, high-Q filters possible at a fraction of their usual size.

By utilising Avago’s advanced Microcap bonded-wafer chip-scale packaging and proprietary FBAR filter technologies, the ACPF-7024 and ACPF-7025 are assembled into moulded chip-on-board modules with a compact size of 2.5 x 2.5mm and 2.0 x 1.6mm respectively.

Applications for the ACPF-7024 and ACPF-7025 include 4G/LTE mobile and 802.11 b/g/n WiLAN/Wi-Fi and Bluetooth data communications in handsets and portable communication devices such as laptops, netbooks and tablet devices.
