BPF-A1340+

Overview

The BPF-A1340+ is a surface-mount lumped LC bandpass filter designed for RF signal conditioning. It operates within a frequency range of 1000 to 1800 MHz, centered at 1.34 GHz with an 800 MHz bandwidth. The component features a 50-ohm impedance and utilizes the HQ1157 case style. Typical performance includes a voltage standing wave ratio (VSWR) of 1.4:1 within the passband. It offers high rejection characteristics and is shielded to minimize interference.

Feature Summary

• Shielded construction for enhanced signal integrity
• High out-of-band rejection capabilities
• Compact surface-mount design suitable for space-constrained applications

Applications

• Wireless communication base stations
• Mobile phone transceivers
• RF wireless modules

Procurement Notes

Verify the specific datasheet version when sourcing, as Mini-Circuits may update electrical specifications or mechanical drawings over time. Confirm that the HQ1157 package dimensions match your PCB footprint requirements. Ensure compatibility with standard SMT reflow processes. Cross-reference the part number suffix to confirm RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a wide 800 MHz bandwidth is required around the 1.34 GHz center frequency. The 50-ohm system impedance makes it suitable for standard RF interfaces. Consider the HQ1157 package size during layout planning. Evaluate the typical VSWR of 1.4:1 against your system's reflection coefficient tolerance. This filter is appropriate for designs prioritizing compactness alongside broad spectral filtering.
