LPF1005LRRLR0709L

Overview

The LPF1005LRRLR0709L is a low-pass filter manufactured by Pulse Electronics, designed for signal conditioning applications. It operates within the LTE Low Band frequency range of 698 MHz to 960 MHz. The component utilizes a surface-mount device (SMD) package with dimensions corresponding to the 1005 metric size (0402 imperial). This filter is engineered to suppress high-frequency noise while allowing lower band signals to pass, supporting telecommunications infrastructure and mobile devices requiring robust RF signal integrity.

Feature Summary

• Provides low-pass filtering characteristics specifically tuned for LTE Low Band frequencies
• Utilizes a compact 1005 metric surface-mount package for space-constrained designs
• Engineered for signal conditioning and EMI/RFI suppression in wireless communication systems

Applications

• LTE Low Band receiver front-ends
• Mobile phone RF signal processing
• Wireless communication base station components

Procurement Notes

Verify the exact manufacturer designation when sourcing, as some distributors list this part under Pulse Electronics while others may reference YAGEO due to historical manufacturing relationships. Confirm the specific suffix LRRLR matches the required impedance and tolerance specifications for your circuit design. Ensure compatibility with standard reflow soldering profiles for 1005 packages. Cross-reference datasheets from authorized suppliers to confirm current RoHS compliance status and lead times, as availability can fluctuate based on production cycles.

Selection Notes

Select this component when designing circuits that require attenuation of frequencies above the 960 MHz threshold while preserving signals between 698 MHz and 960 MHz. The 1005 package size is suitable for dense PCB layouts common in modern smartphones and IoT devices. Consider the insertion loss and return loss parameters specified in the official datasheet to ensure they meet your system's sensitivity requirements. Compare against other low-pass filters in the same series if different cutoff frequencies or power handling capabilities are needed.

Part Context

This part belongs to the family of RF filters produced by Pulse Electronics, often associated with their acquisition of YAGEO's passive component lines. These filters are critical for maintaining signal purity in cellular communication modules. The LPF1005 series typically includes various configurations tailored for different LTE bands and GSM standards, offering standardized solutions for mass-produced electronic devices.

Replacement Considerations

Direct substitutes include LPF1005LM55R0709A and LPF1005CNR0709L, which share similar frequency ranges and package types. Verify electrical performance equivalence before substitution. Other compatible parts may include LPF1005LRRLR0709L variants with slight parameter differences.
