Overview
The RLP-470+ is a lumped LC low-pass filter designed for RF applications with a cutoff frequency of 470 MHz. It operates within a 50 Ohm impedance system and supports an input power of up to 0.5W. The device provides attenuation characteristics including less than 2dB loss in the passband (DC-470MHz), greater than 20dB loss at 650-780MHz, and greater than 40dB loss from 780-2000MHz. It functions reliably between -40°C and 85°C.
Feature Summary
- Lumped LC architecture for compact integration
- High stopband rejection exceeding 40dB above 780MHz
- SMD/SMT termination style for surface mount assembly
Applications
- RF signal conditioning in communication systems
- Harmonic suppression in transmitter outputs
- Interference filtering in receiver front-ends
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets all environmental ratings and maximum power handling requirements for your specific operational context before finalizing procurement.
Selection Notes
Select this component when a sharp roll-off is required below 1GHz with minimal insertion loss in the baseband region. Ensure the design accommodates the physical footprint dimensions and thermal constraints associated with the SMD package. Validate impedance matching networks to maintain performance within the specified 50 Ohm system.
Part Context
This part belongs to Mini-Circuits' RLP series of lumped element filters. These components utilize discrete LC structures rather than distributed transmission lines, allowing for smaller form factors suitable for dense PCB layouts while maintaining effective filtering performance across the specified frequency range.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Verify electrical compatibility regarding cutoff frequency, impedance, and power handling if considering cross-brand replacements.
FAQ
What is the maximum input power rating?
The maximum RF power input is rated at 0.5W.
Does the filter support DC signals?
Yes, the passband extends from DC to 470 MHz.
