ACFF-1024
ISM Bandpass Filter (2401 – 2482 MHz)
Data Sheet
Description
The Avago ACFF-1024 is a miniaturized Bandpass Filter
designed for use in the 2.4 GHz Industrial, Scientific and
Medical (ISM) band.
The ACFF-1024 is designed to enable concurrent opera-
tion of Wireless LAN and Bluetooth applications that coex-
ist with other wireless standards, such as 2.5 GHz WiMAX,
PCS, and LTE Bands 7 and 40, without performance degra-
dations due to interference.
The ACFF-1024 is designed with Avago Technologies’ in-
novative Film Bulk Acoustic Resonator (FBAR) technology,
which makes possible ultra-small, high-Q filters at a frac-
tion of their usual size.
The ACFF-1024 also utilizes Avago Technologies’advanced
Microcap bonded-wafer technology. This chip scale min-
iaturization process results in a package size of only 1.4 x
1.1 mm and maximum height of 0.80 mm.
The ACFF-1024 is compatible with high volume, lead-free
SMT soldering processes and can be direct surface mount-
ed to a PCB or a transfer molded module.

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, unless otherwise noted.
3. Unless otherwise noted, Typical data is the average value (arithmetic mean) of the parameter over the indicated band at 25 °C.
4. Channel average Insertion Loss, which is obtained by averaging |S21| over the center 19 MHz of channels and converting to dB value.
5. Channel average Insertion Loss, which is obtained by averaging |S21| over 5 MHz channels and converting to dB value.

Notes:
1. Operation in excess of any one of these conditions may result in permanent damage to the device.
2. The device will function over the recommended range without degradation in reliability or permanent change in performance, but is not
guaranteed to meet electrical specifications.
3. Tc is defined as case temperature, the temperature of the underside of the Filter where it makes contact with the circuit board.
4. The ACFF-1024 is not symmetrical. Port 1 (Pin 1) is designed for higher power handling and is connected to the Tx/Rx blocks; Port 2 (Pin 4) is
connected to the system Antenna.
