BPF1005LRPKR3750A

Overview

The BPF1005LRPKR3750A is a bandpass filter manufactured by Pulse Electronics, designed for signal conditioning applications. It operates within a frequency range of 3.3 GHz to 4.2 GHz, with a center frequency of 3.75 GHz and a bandwidth of 900 MHz. The component features a 50 Ohm impedance and utilizes an SMD/SMT termination type in a 0402 (1005 metric) package. It supports board mounting and functions across a temperature range of -40°C to +85°C. The insertion loss is specified at 1.07 dB.

Feature Summary

• LTCC technology implementation for compact RF filtering
• High selectivity bandpass response centered at 3.75 GHz
• Surface-mount compatibility with standard 0402 footprint

Applications

• Wireless communication modules requiring 3.3-4.2 GHz filtering
• RF front-end signal conditioning in mobile devices
• IoT sensor nodes operating in the ISM band

Procurement Notes

Verify RoHS compliance status through official manufacturer documentation prior to integration. Confirm that the specific suffix 'A' aligns with required passband specifications, as variations may exist within the BPF series. Ensure thermal management strategies account for the -40°C to +85°C operational range during final product validation.

Selection Notes

Select this component when a 0402 footprint is mandatory for space-constrained designs. The 900 MHz bandwidth suits applications needing moderate channel separation. Compare insertion loss metrics against system noise requirements. Verify impedance matching networks are optimized for 50 Ohm systems to minimize reflection losses at the 3.75 GHz center frequency.

Part Context

This part belongs to Pulse Electronics' BPF series of LTCC bandpass filters. These components are engineered for high-frequency RF applications where size reduction is critical. The series typically offers consistent performance across various center frequencies, allowing designers to scale solutions while maintaining standardized packaging and mounting characteristics.

Replacement Considerations

Cross-reference with BPF1005LRPPR3750L for similar 3.75 GHz center frequency applications. Verify if alternative suffixes like 'QRR' or 'LRP' offer compatible bandwidths. Ensure substitute parts maintain identical 0402 dimensions and 50 Ohm impedance to preserve PCB layout integrity.
