BFTC-615+

Overview

The BFTC-615+ is an LTCC bandpass filter manufactured by Mini-Circuits. It operates with a center frequency of 615 MHz and a bandwidth of 330 MHz, covering the 450 to 780 MHz passband. The component provides 25 dB upper and lower stopband rejection. It features 6 dB insertion loss and is designed for 50 Ohm systems. The device utilizes a 6-SMD, no lead package with dimensions of 0.150 inches by 0.150 inches (3.81 mm x 3.81 mm).

Feature Summary

• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for compact surface-mount integration.
• Provides high stopband rejection of 25 dB on both upper and lower sides.
• Designed for 50 Ohm impedance matching in RF signal paths.

Applications

• RF front-end filtering in communication systems
• Signal conditioning in wireless infrastructure
• Frequency selection in microwave components

Procurement Notes

Verify the specific datasheet version when sourcing the BFTC-615+. Confirm that the required package type matches the 6-SMD no-lead configuration. Ensure the operating environment aligns with the component's moisture sensitivity level specifications. Cross-reference the electrical parameters against the official Mini-Circuits documentation to guarantee compatibility with the intended circuit design requirements.

Selection Notes

Select this component when a narrow bandpass characteristic is required around 615 MHz. The LTCC construction supports reliable performance in space-constrained designs. Consider the 6 dB insertion loss when calculating system gain budgets. The 50 Ohm impedance ensures compatibility with standard RF transmission lines and matching networks used in typical radio frequency applications.

Part Context

This part belongs to the BFTC series of LTCC bandpass filters from Mini-Circuits. The series offers various center frequencies tailored for different RF applications. These components are engineered for high reliability and consistent performance across microwave frequencies. The BFTC-615+ specifically targets the VHF/UHF range with defined bandwidth constraints.

Replacement Considerations

Consult official Mini-Circuits substitution guides for verified alternatives. Ensure any substitute maintains the 615 MHz center frequency and 330 MHz bandwidth. Verify that the replacement component matches the 6-SMD no-lead package footprint. Confirm that electrical parameters such as insertion loss and rejection levels meet or exceed the original specifications.
