TBP-154+

Overview

The TBP-154+ is a surface-mount bandpass filter designed for RF applications. It operates within a passband of 136 MHz to 175 MHz, providing signal selection in this specific frequency range. The component features a characteristic impedance of 50 Ohms, ensuring compatibility with standard RF systems. Fabricated using SMT technology, it is housed in a shielded package measuring 0.25 inches by 0.25 inches by 0.10 inches (approximately 6.35 mm x 6.35 mm x 2.54 mm). This compact form factor supports integration into space-constrained circuit designs while maintaining electrical performance.

Feature Summary

• Shielded surface-mount construction for electromagnetic interference protection
• Broad-band bandpass filtering capability centered on the 136-175 MHz range
• Standard 50 Ohm impedance matching for seamless RF system integration

Applications

• RF receiver front-end filtering
• Transmitter output stage filtering
• General-purpose RF signal conditioning

Procurement Notes

Verify the exact datasheet version and revision history from Mini-Circuits or authorized distributors before procurement. Confirm that the 50 Ohm impedance specification aligns with your system requirements. Ensure the SMT footprint dimensions match your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards. Validate that the operating temperature range meets your environmental conditions.

Selection Notes

Select the TBP-154+ when a fixed bandpass response between 136 MHz and 175 MHz is required. Its 50 Ohm impedance makes it suitable for standard RF infrastructure. The shielded SMT package offers advantages in high-density layouts where size and isolation are critical. Consider its broad-band characteristics if adjacent channel rejection is less critical than wide passband coverage. Evaluate thermal management needs based on the specified operating temperature limits.

Part Context

Mini-Circuits specializes in RF, IF, and microwave components ranging from DC to 86 GHz. The TBP-154+ belongs to their line of surface-mount filters, which are engineered for reliability and consistent performance in commercial and industrial applications. These components are widely used in telecommunications, test equipment, and wireless infrastructure due to their standardized impedance and compact packaging solutions.

Replacement Considerations

Consult Mini-Circuits official documentation for direct cross-reference part numbers. Verify that any substitute maintains the 136-175 MHz passband and 50 Ohm impedance. Ensure physical footprint compatibility for SMT assembly. Confirm that shielding characteristics and insertion loss specifications meet original design requirements.
