5235BP45A0180001E

Overview

The Johanson Technology Inc. model 5235BP45A0180001E is a surface-mount bandpass RF filter designed for the 5.235 GHz center frequency. It operates within a frequency range of 5.17 GHz to 5.33 GHz, providing a bandwidth of 180 MHz. The component features an insertion loss of 2.5 dB and utilizes a 5-SMD, no-lead package suitable for board mounting.

Feature Summary

• Provides selective signal filtering in the 5 GHz unlicensed band
• Supports compact surface-mount integration via a 5-terminal leadless package
• Designed for stable operation across specified industrial temperature ranges

Applications

• Wi-Fi 6/6E wireless local area network (WLAN) systems
• Bluetooth Low Energy (BLE) transceivers operating in the 5 GHz spectrum
• Zigbee and IEEE 802.15.4 communication modules
• 5G NR sub-6 GHz receiver front-end stages

Procurement Notes

Verify the specific suffix 'E' against the manufacturer's current global part numbering change documentation to ensure compatibility with RoHS3 standards. Confirm that the 5-SMD no-lead footprint matches the target PCB land pattern dimensions precisely before finalizing procurement orders.

Selection Notes

Select this component when a narrow 180 MHz passband is required around 5.235 GHz. Ensure the design accommodates the 2.5 dB insertion loss budget. Verify that the operating environment stays within the -40°C to +85°C temperature limits defined for the BP series family.

Part Context

This device belongs to the Johanson Technology BP series of ceramic bandpass filters. These components are engineered for high-reliability applications in crowded RF environments. The series offers consistent performance characteristics for multi-band wireless protocols requiring precise frequency isolation.

Replacement Considerations

Cross-reference with Johanson model 5235CR45A0180001U for similar electrical specifications. Verify mechanical footprint compatibility between the CR and BP series packages before substitution.
