1200BP44A0575001E

Overview

The 1200BP44A0575001E is a surface-mount bandpass filter manufactured by Johanson Technology. It operates within a frequency range of 950 MHz to 1525 MHz, centered at 1.2375 GHz with a bandwidth of 575 MHz. The component features an insertion loss of 2.8 dB and a return loss of 7.0 dB. It is housed in an 1812 (4532 metric) package and supports board mount installation via SMD/SMT termination.

Feature Summary

• Provides signal conditioning through bandpass filtering capabilities
• Designed for surface-mount technology integration
• Supports operation across wideband RF frequencies

Applications

• RF signal conditioning circuits
• Wireless communication systems
• General purpose RF filtering applications

Procurement Notes

Verify the specific datasheet version before procurement, as legacy part numbers such as 1200BP44A575 may exist. Confirm that the 1812 package dimensions align with your PCB footprint requirements. Ensure the 2.8 dB insertion loss meets your system budget. Check for any regional distribution restrictions or limited availability status prior to ordering.

Selection Notes

Select this component when a wideband filter covering the 950-1525 MHz range is required. The 1812 package offers a balance between performance and board space. Consider the 2.8 dB insertion loss impact on overall link budget. Verify compatibility with standard SMD assembly processes. This filter is suitable for applications requiring moderate selectivity in the sub-2 GHz spectrum.

Part Context

This component belongs to Johanson Technology's RF filter portfolio, specifically designed for signal conditioning. It utilizes ceramic resonator technology typical of the brand's passive components. The device serves as a passive element in RF front-end designs, distinguishing itself from active amplifiers or mixers by providing frequency selection without gain.

Replacement Considerations

The legacy part number 1200BP44A575 is identified as a predecessor. Verify electrical equivalence if substituting. No other direct cross-references are documented in available public sources.
