1900HP41A0500001E

Overview

The Johanson Technology 1900HP41A0500001E is a high-pass RF filter designed for signal conditioning applications. It operates with a center frequency of 1.9 GHz and covers a frequency range from 1650 MHz to 2150 MHz, providing a bandwidth of 500 MHz. The component features an insertion loss of 2.0 dB and a return loss of 8.5 dB. It utilizes a 1210 (3225 Metric) surface-mount package with four pad connections. This device is part of the High Pass Filters product category.

Feature Summary

• Provides high-pass filtering characteristics centered at 1.9 GHz
• Utilizes a compact 1210 surface-mount package design
• Engineered for radio frequency signal conditioning

Applications

• RF front-end modules requiring high-pass filtering
• Wireless communication systems operating near 1.9 GHz
• Signal conditioning circuits in mobile devices

Procurement Notes

Verify the specific suffix 'A' against official Johanson Technology documentation to confirm pinout and electrical tolerances. Ensure the 1210 package dimensions match your PCB footprint requirements. Cross-reference the legacy part number 1900HP41A0500E if sourcing from older inventory lists. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement.

Selection Notes

Select this component when a 1.9 GHz high-pass response is required within the 1650-2150 MHz range. The 2.0 dB insertion loss specification should be evaluated against system link budget constraints. The 1210 package size offers a balance between performance and board space efficiency compared to smaller footprints. Consider the 8.5 dB return loss for impedance matching requirements in the specific circuit topology.

Part Context

This component belongs to Johanson Technology's portfolio of SAW diplexers and filters. It serves as a specialized signal conditioning element within the broader category of radio frequency components. The part is distinct from low-pass or band-pass variants in the same series, specifically targeting high-frequency rejection below the 1.9 GHz passband.

Replacement Considerations

The legacy part number 1900HP41A0500E is documented as a predecessor. Verify functional equivalence and parameter alignment with official substitution guides before replacing the current model.
