BBP-70+

Overview

The BBP-70+ is a lumped LC band pass filter manufactured by Mini-Circuits, designed for radio frequency signal conditioning. It operates within a frequency range of 63 to 77 MHz with a center frequency of 70 MHz and a bandwidth of 14 MHz. The component features a 50-ohm impedance and utilizes BNC connectors for in-line module integration. Constructed in the FF55 case style, it supports an operating temperature range from -55°C to +100°C. This filter provides a typical insertion loss of 1.5 dB, ensuring efficient signal transmission within its specified passband while maintaining standard RF interface compatibility.

Feature Summary

• Lumped LC band pass filter design for precise frequency selection
• BNC connector interface for direct in-line module integration
• Wide operational temperature range suitable for harsh environments
• Standard 50-ohm impedance matching for RF systems

Applications

• Radio frequency signal filtering in communication equipment
• Intermediate frequency (IF) stage filtering in receivers
• Test and measurement instrumentation signal conditioning
• Broadband amplifier input/output filtering

Procurement Notes

Verify the specific datasheet revision and electrical performance graphs directly from Mini-Circuits or authorized distributors before procurement. Confirm that the BNC connector type and FF55 package dimensions align with your system requirements. Ensure environmental ratings meet your operational temperature needs. Cross-reference the manufacturer part number to avoid confusion with similar low-pass variants like the BLP-70+. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select the BBP-70+ when a fixed center frequency of 70 MHz with a 14 MHz bandwidth is required. It is suitable for applications needing low insertion loss and high rejection outside the passband. Consider this component for systems utilizing BNC interfaces where plug-and-play simplicity is preferred over surface-mount solutions. Evaluate the thermal performance against your ambient conditions, as it supports extended temperature ranges. Compare specifications against other Mini-Circuits filters if tighter bandwidths or different impedances are needed.

Part Context

The BBP-70+ belongs to Mini-Circuits' extensive portfolio of RF and microwave components, specifically within their band pass filter category. It complements other signal conditioning devices such as low-pass filters (e.g., BLP-70+) and amplifiers. Designed for versatility, it fits into modular RF test setups and production environments. The component reflects Mini-Circuits' focus on providing reliable, cost-effective building blocks for frequencies ranging from DC to high microwave bands, supporting both laboratory and industrial applications.

Replacement Considerations

Direct substitutes may include other Mini-Circuits band pass filters with similar center frequencies and bandwidths, such as those in the BBP series. Verify electrical parameters like insertion loss and return loss before substitution. Alternative manufacturers may offer comparable components, but connector types and package styles must match for mechanical compatibility. Always consult official datasheets to ensure functional equivalence.
