LFB2H2G45SG7A159

Overview

The LFB2H2G45SG7A159 is a ceramic band-pass filter manufactured by Murata Electronics, designed for communication equipment applications. It operates with a center frequency of 2.45 GHz and provides a bandwidth of 50 MHz. The component features a nominal impedance of 50 Ohms and supports a maximum power capacity of 1W. It is housed in a compact 1008 (2520 Metric) surface-mount package. The device is rated for an operating temperature range from -40°C to +85°C and complies with RoHS standards.

Feature Summary

• Provides precise signal filtering within the 2.45 GHz ISM band using ceramic resonator technology.
• Designed for high-power handling capabilities suitable for RF front-end modules.
• Utilizes a small footprint surface-mount package for efficient PCB layout integration.

Applications

• Wireless LAN (WLAN) systems operating at 2.4 GHz
• Bluetooth low energy (BLE) transceivers
• Industrial, Scientific, and Medical (ISM) radio equipment

Procurement Notes

Verify current availability status as the component may be subject to obsolescence notices. Confirm that the ordering suffix matches the required package type and tape/reel specifications. Ensure compliance with RoHS3 requirements for environmental regulations. Check for moisture sensitivity level classifications prior to soldering processes.

Selection Notes

Select this component when a narrow 50 MHz bandwidth is required around the 2.45 GHz center frequency. Consider the 1008 package size for space-constrained designs. Evaluate the 50 Ohm impedance match against system requirements. Verify thermal performance within the specified -40°C to +85°C operational range.
