The BPF-A1140+ is a 50Ω surface mount bandpass filter designed for radio astronomy and defense systems, operating from 840 to 1440 MHz. It features a miniature shielded HQ1157 package measuring 9.27 × 34.54 × 8.89 mm, with a pass band insertion loss of 2.5 to 4.0 dB, maximum VSWR of 1.9:1 within the pass band, and rejection of at least 20 dB in stop bands below 711 MHz and above 1577 MHz. The filter operates reliably from -40°C to 85°C and handles up to 1 W RF power input. It is RoHS compliant.
The BPF-A1140+ is a 50Ω 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.
