ACPF-7024 ISM Bandpass Filter (2401 – 2482 MHz)
Data Sheet
Description
The Avago ACPF-7024 is a miniaturized Bandpass Filter designed for use in the 2.4 GHz Industrial, Scientific and Medical (ISM) band.
The ACPF-7024 is designed to enable concurrent operation of Wireless LAN and Bluetooth applications which coexist with other wireless standards, such as 2.5 GHz WiMAX, PCS, and LTE Bands 7 and 40, without performance degradations due to interference.
The ACPF-7024 is designed with 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-7024 also utilizes Avago Technologies’advanced Microcap bonded-wafer technology. This chip scale miniaturization process results in a package footprint of only 1.6 x 2.0 mm with a maximum height of 0.95 mm
The ACPF-7024 is compatible with high volume, lead-free SMT soldering processes and can be direct surface mounted 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). Ports 1 and 2 are interchangeable (Filter is
symmetrical). 3. Typical data is the average value (arithmetic mean) of the parameter over the indicated band at the specified temperature range. 4. Average insertion Loss with constant weighting over indicated frequency range.

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.
