Operating temperature^[1] ......-30°C to +85°C
Storage temperature^[1]...... -30°C to +100°C
Notes:
1. Temperature is defined at case T_C, the temperature of the underside of the filter where it makes contact with the circuit board.
2. Specifications are guaranteed over the given temperature range. Operation in excess of any one of these conditions may result in permanent damage to the device.

The ACPF- 7002 is a high rejection full band transmit filter designed for US PCS handsets. Its performance rivals splitband surface acoustic wave (SAW) transmit filters. Since a single filter provides the rejection, no switches are required, saving board space and external components,eliminating switch loss, and reducing programming complexity.

The ACPF- 7002 FBAR transmit filter utilizes Agilent's Microcap bonded- wafer chip scale packaging technology. This process allows the ultra small filters to be assembled into a Molded Chip on Board (MCOB) module.

In typical cellular phone architectures, the transmit ACPF-7002 filter fits between the driver amplifier and the Power Amplifier. The
ACPF- 7002 FBAR filter reduces the noise in the Rx band being amplified by the transmit chain,enhancing receiver sensitivity.High rejection keeps unwanted signals out of the receive path.

Agilent's thin-Film Bulk Acoustic Resonator (FBAR) technology makes possible high-Q filters ACPF-7002 at a fraction their usual size.
