BPF-B157+

The BPF-B157+ is a surface mount band pass filter from Mini-Circuits designed for the 151 to 163 MHz passband with a center frequency of 157 MHz. It features a bandwidth of 12 MHz and a characteristic impedance of 50 Ω, making it suitable for RF communication systems. The filter provides a maximum insertion loss of 3.5 dB within the passband, with a typical insertion loss of 2.17 dB at 157 MHz. Typical VSWR is 1.1:1 across the passband, with a maximum of 1.4:1. Return loss at 157 MHz is typically 31.79 dB. Stopband attenuation is at least 20 dB at 131 MHz and 187 MHz, and at least 40 dB at 115 MHz and 215 MHz. Group delay at 157 MHz is typically 35.02 ns. The filter is housed in a 6-SMD, no lead package (case style HZ1198) with dimensions 20.98 mm x 11.99 mm x 5.59 mm. It operates over a temperature range of -40°C to 85°C and can handle up to 0.5 W RF input power. The component is RoHS3 compliant and suitable for automated assembly in surface mount applications.
