ACFF-1025
LTE Band 41 Bandpass Filter
Data Sheet
Description
The Avago ACFF-1025 is a highly miniaturized LTE Band
41 (2496 – 2690 MHz) bandpass filter combined with a
WLAN/Wi-Fi band reject filter.
The ACFF-1025 is designed to operate in WiMAX trans-
ceiver applications which coexist with WLAN, Wi-Fi and/or
Bluetooth transmitters.
The ACFF-1025 is designed with Avago Technologies’
innovative Film Bulk Acoustic Resonator (FBAR) technol-
ogy, which makes possible ultra-small, high-Q filters at a
fraction of their usual size. The excellent power handling
capability of FBAR bulk-mode resonators supports the
high output power levels used in mobile communications
applications, while adding virtually no distortion.
The ACFF-1025 also utilizes Avago Technologies’advanced
Microcap bonded-wafer, chip scale packaging technol-
ogy. This process allows the filter to be assembled into a
molded chip-on-board module with an overall size of 2.5
x 2.5 mm and height of 1.0 mm.

Notes:
1. TC is the case temperature and is defined as the temperature of the underside of the filter where it makes contact with the circuit board.
2. Min/Max specifications are guaranteed at the indicated temperature with the input power to the Tx/Rx port equal to or less than +25 dBm over all
Tx/Rx frequencies unless otherwise noted.
3. Typical data is the average value of the parameter over the indicated band at the specified temperature. Typical values may vary over time.
