ACPF-7141
Bandpass Filter for LTE Band 41
Data Sheet
Description
The Avago ACPF-7141 is a miniature Bandpass Filter de-
signed for use in LTE Band 41 (2496 – 2690 MHz) wireless
applications.
The ACPF-7141 is designed to enable concurrent op-
eration of Band 41 with applications in adjacent 2.4 GHz
Bands (Wi-Fi, WLAN, Bluetooth, ISM).
The ACPF-7141 utilizes Avago Technologies’ innovative
Film Bulk Acoustic Resonator (FBAR) technology, which
makes possible ultra-small, high-Q filters at a fraction of
their usual size.
The ACPF-7141 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. Min./Ma.x. specifications are guaranteed at the indicated temperature, unless otherwise noted.
2. T
C
is the case temperature and is defined as the temperature of the underside of the filter where it makes contact with the circuit board.
3. Typical data is the average value (arithmetic mean) of the parameter over the indicated band at +25
°C.
4. Wi-Fi Channel Average Attenuation, which is obtained by averaging |S21| over the center 19 MHz of the 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 ACPF-7141 is not symmetrical. Pin 1 is designed for higher power handling and is intended to be connected to the Tx blocks with Pin 2
connected to the system antenna.
3. Internal DC resistance of any port to ground or between ports is approximately a short circuit.
4. 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.
5. T
C
is defined as case temperature, the temperature of the underside of the filter where it makes contact with the circuit board.
Applications Information
The ACPF-7141 is not symmetrical. Pin 1 should be connected to the highest system power level (e.g., Tx block) and Pin
2 to the Antenna.
The DC resistance from Pin 1 and Pin2 to Gnd is approximately zero. If either port is connected to adjacent components
having a DC voltage present, blocking capacitors should be used.
