Avago introduces two FBAR Filter technology based band pass filters for 4G WiMAX/LTE Handsets

Avago has unveiled two advanced Film Bulk Acoustic Resonator (FBAR) technology-based bandpass filters for next generation 4G WiMAX/LTE handsets, data cards and access points.

The 2400-2482 MHz WiFi/Bluetooth bandpass filter ACPF-7024 operates without any performance degradation due to radio interference from other wireless standards—such as 2.5 GHz WiMAX, PCS, and LTE Bands 7 and 40. The ACPF-7024 offers 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.

The ACPF-7025 and ACPF-7024 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
