BPF-F1250+

Overview

The BPF-F1250+ is a lumped LC bandpass filter designed for RF applications. It operates with a center frequency of 1.25 GHz and provides a bandwidth of 400 MHz, covering the range from 1050 to 1450 MHz. The component maintains a 50 Ohm impedance and exhibits an insertion loss of 2 dB. It is housed in an 18-SMD, no-lead package, specifically the HP1156 case style, utilizing surface-mount technology.

Feature Summary

• Utilizes lumped LC topology for precise frequency selection
• Features a shielded SMT package for signal integrity
• Designed for low insertion loss within the passband

Applications

• L-band wireless communication systems
• RF front-end filtering modules
• EMI/RFI suppression circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required termination styles or tolerance levels. Confirm that the HP1156 package dimensions align with your PCB footprint constraints before finalizing procurement orders.

Selection Notes

Select this component when a fixed center frequency of 1.25 GHz is required with a 400 MHz bandwidth. Ensure the design accommodates the 18-SMD no-lead package profile. Consider the 2 dB insertion loss impact on system noise figure during link budget calculations.

Part Context

Mini-Circuits manufactures a broad portfolio of passive RF components including filters, couplers, and splitters. The BPF-F1250+ belongs to their active bandpass filter category, serving as a specialized solution for narrowband signal conditioning in microwave and radio frequency environments.

Replacement Considerations

Consult official Mini-Circuits substitution guides for equivalent performance. Verify that any alternative part matches the 1.25 GHz center frequency, 400 MHz bandwidth, and 18-SMD package form factor.
