Surface Mount Bandpass Filter BPF-A1140+ 50 840 to 1440 MHz The Big Deal Wide bandwidth Generic photo used for illustration purposes only Better rejection CASE STYLE: HQ1157 Miniature shielded package Product Overview The BPF-A1140+ is a 50 bandpass filter fabricated using SMT technology. This bandpass filter covers from 840- 1440 MHz. This filter is built with high Q capacitors and air-coil inductors for superior performance. This filter is devel- oped for square kilometer array telescope systems for radio astronomy. It has repeatable performance across lots and consistent performance across temperature. Key Features Feature Advantages Low insertion loss Can be used in high performance applications such as radio astronomy. Good rejection This enables the filter to attenuate spurious signals and reject harmonics for broad frequency band. Shielded case Reduced interference with and from the surrounding components.
