PLP-5+

Overview

The PLP-5+ is a lumped LC low-pass filter designed for RF applications with a cutoff frequency of 6 MHz. It operates within a 50-ohm impedance system and supports an average input power of 0.5 W. The device features a nominal cutoff frequency (fc) of 6 MHz, providing signal conditioning from DC up to the specified bandwidth while attenuating higher frequencies.

Feature Summary

• Lumped LC architecture for compact signal filtering
• Low-pass response characteristic with defined cutoff
• Hermetically sealed rugged welded case construction

Applications

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

Procurement Notes

Verify the specific datasheet revision and electrical performance graphs directly from Mini-Circuits or authorized distributors. Confirm that the 6 MHz cutoff specification aligns with your system requirements. Ensure compatibility with 50-ohm system impedance and check thermal management needs for continuous 0.5 W operation.

Selection Notes

Select this component when a sharp low-pass response is required below 10 MHz. The hermetic package suits harsh environments. Compare insertion loss and stopband attenuation against other Mini-Circuits filters like the PLP-550+ if higher frequency ranges are needed.

Part Context

This part belongs to Mini-Circuits' line of plug-in low-pass filters. It utilizes lumped LC elements rather than distributed transmission lines, offering a smaller form factor compared to waveguide alternatives. The '+' suffix typically indicates RoHS compliance.

Replacement Considerations

Direct substitutes include the PLP-5 (non-RoHS version). For higher frequency applications, consider the PLP-550+. Verify mechanical footprint and pinout compatibility before replacing existing units in legacy designs.
