Overview
The ZX75LP-70-S+ is a lumped LC low pass filter manufactured by Mini-Circuits. It operates within a frequency range of DC to 70 MHz and features a 50 Ohm impedance. The device utilizes SMA connectors for interface termination. It is designed for signal conditioning applications requiring effective high-frequency attenuation.
Feature Summary
- Lumped LC architecture for compact signal filtering
- SMA connectorized package for direct system integration
- Optimized matching characteristics within the passband
Applications
- RF signal conditioning circuits
- Base station front-end filtering
- Test and measurement equipment input stages
Procurement Notes
Verify the specific suffix 'S+' indicates SMA connectors against the official Mini-Circuits datasheet. Confirm the part number matches the exact 70 MHz cutoff specification required for your design. Ensure environmental ratings align with operational temperature ranges.
Selection Notes
Select this component when a discrete, connectorized low-pass solution is preferred over surface-mount alternatives. The 50 Ohm impedance ensures compatibility with standard RF transmission lines. Verify that the lumped LC topology meets the specific harmonic rejection requirements of the application.
Part Context
This component belongs to the ZX75LP series of low pass filters from Mini-Circuits. The series offers various cutoff frequencies while maintaining consistent 50 Ohm impedance and connectorized packaging styles suitable for prototyping and production environments.
Replacement Considerations
Consult the Mini-Circuits ZX75LP series catalog for alternative cutoff frequencies such as ZX75LP-105-S+ or ZX75LP-70-S+. Verify mechanical footprint and connector type compatibility before substitution.
