Operating temperature^[1] -30 to +85°C

Notes:
1. TC is defined as case temperature, the temperature of the underside of the duplexer where it makes contact with the circuit board.

2. Specifications are given at operating temperature limits and room temperature. To estimate performance at some intermediate temperature, use linear interpolation.

3. Specifications are guaranteed over the given temperature range, with the input power to the Tx port equal to +30 dBm (or lower) over all Tx frequencies. The application of input power levels in excess of +30 dBm will not destroy the duplexer, but its performance may exceed the specification limits given above.

4. Operation in excess of any one of these conditions may result in permanent damage to the device.

The HPMD-7905 is a miniaturized duplexer designed for US PCS handset, designed using Agilent Technologies' Film Bulk Acoustic Resonator (FBAR) Technology. It features a very small size: it is less than 2 mm thick and has a footprint of only 5.6 x 11.9 mm2.

The HPMD-7905 enhances the sensitivity and dynamic range of CDMA receivers, providing morethan 49 dB attenuation of transmitted signal at the receiver input, and more than 37 dB rejection of the transmitgenerated noise in the receive band. Typical insertion loss in the Tx channel is only 2.5 dB, minimizing current drain from the power amplifier. Typical insertion loss in the Rx channel is 3.0 dB, improving receiver sensitivity.

Agilent's thin-Film Bulk Acoustic Resonator (FBAR) technology makes HPMD-7904 possible high-Q filters at a fraction their usual size. The excellent power handling of the bulk-mode resonators supports the high output powers needed in PCS handsets, with virtually no added distortion.
