1810BP07B0200001T

Overview

The Johanson Technology Inc. 1810BP07B0200001T is a surface-mount bandpass RF filter designed for signal conditioning applications. It operates with a center frequency of 1.81 GHz and supports a frequency range from 1.7 GHz to 1.91 GHz. The component features a 200 MHz bandwidth and maintains a system impedance of 50 Ohms. Key electrical specifications include an insertion loss of 2 dB and a return loss of 9.5 dB. It is housed in a compact 0402 (1005 Metric) package, measuring 1.00 mm x 0.50 mm with a maximum height of 0.43 mm.

Feature Summary

• Provides selective frequency filtering within the specified 1.7 GHz to 1.91 GHz range
• Utilizes a low-profile surface mount design for space-constrained circuit layouts
• Maintains consistent 50 Ohm impedance matching for standard RF transmission lines

Applications

• Wireless communication systems operating in the 1.8 GHz spectrum
• RF front-end modules requiring bandpass signal conditioning
• Mobile device antenna interfaces and transceiver circuits

Procurement Notes

Verify the manufacturer part number against official Johanson Technology documentation to ensure authenticity. Confirm that the specific suffix matches the required RoHS compliance status and packaging format. Cross-reference legacy identifiers such as 1810BP07B200 if integrating into existing designs. Ensure compatibility with standard SMT assembly processes given the 0402 footprint dimensions.

Selection Notes

Select this component when a precise 1.81 GHz center frequency is required for narrowband applications. The 200 MHz bandwidth offers sufficient selectivity for adjacent channel rejection while maintaining low insertion loss. The 0402 package size is suitable for high-density PCB layouts where larger footprints are impractical. Verify thermal and mechanical constraints align with the specified operating temperature range.

Part Context

This component belongs to Johanson Technology's integrated passive device portfolio, specifically engineered for radio frequency signal processing. It serves as a critical element in modern wireless infrastructure, enabling efficient spectrum utilization. The product line emphasizes miniaturization without compromising electrical performance metrics essential for reliable data transmission.

Replacement Considerations

The legacy part number 1810BP07B200 represents the same functional unit under previous naming conventions. Substitution requires verification of identical electrical parameters and physical footprint compatibility. No alternative cross-model substitutes are documented in public sources.
