RLP-216+

Overview

The Mini-Circuits RLP-216+ is a lumped LC low-pass filter designed for RF signal conditioning applications. It operates with a nominal impedance of 50Ω and provides a passband from DC to 216 MHz. The component features a cutoff frequency at 232 MHz, ensuring effective attenuation of higher frequencies. Stopband performance includes loss greater than 20 dB from 295 to 340 MHz and greater than 40 dB from 340 to 1300 MHz. It supports a maximum RF power input of 0.5W and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Lumped LC architecture for compact signal filtering
• 50Ω system impedance compatibility
• High stopband attenuation extending to 1300 MHz

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in transmitter outputs
• Interference rejection in receiver front-ends

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm electrical tolerances and thermal ratings before integration. Ensure that the operating environment remains within the specified -40°C to 85°C range to maintain performance stability. Confirm that the applied RF power does not exceed the 0.5W maximum rating to prevent component damage or degradation.

Selection Notes

Select this component when a sharp roll-off is required below 300 MHz with minimal insertion loss in the passband. The 8-SMD no-lead package facilitates surface-mount assembly. Consider the 50Ω impedance match for standard RF circuits. Evaluate the stopband requirements against the specified attenuation levels at 295 MHz and above to ensure adequate interference suppression for the target application.

Part Context

The RLP-216+ belongs to Mini-Circuits' line of lumped element low-pass filters. These components utilize discrete LC networks rather than distributed transmission lines, offering smaller form factors suitable for dense PCB layouts. The series targets applications requiring precise frequency control in the VHF and lower UHF bands.

Replacement Considerations

Consult official Mini-Circuits substitution guides for verified equivalents. Cross-referencing requires matching cutoff frequency, impedance, and package dimensions.
