ZX75LP-40-S+

Overview

The ZX75LP-40-S+ is a lumped LC low pass filter manufactured by Mini-Circuits, designed for signal conditioning applications. It operates within a frequency range of DC to 40 MHz and features a standard 50 Ohm impedance. The device utilizes SMA connectors for interface and is housed in the KE1467 case style. It supports an operating temperature range from -40°C to +85°C. This component provides effective filtering characteristics suitable for RF systems requiring precise bandwidth control.

Feature Summary

• Lumped LC architecture for compact signal conditioning
• SMA connectorized package for easy integration
• Broadband performance from DC to specified cutoff

Applications

• RF signal processing systems
• Communication equipment filtering
• Test and measurement instrumentation

Procurement Notes

Verify the specific datasheet revision and environmental rating (ENV28T5) against project requirements. Confirm that the SMA connector type matches the system interface needs. Ensure the operating temperature range meets the deployment environment specifications. Cross-reference the part number with official Mini-Circuits documentation to confirm current availability and manufacturing status before finalizing procurement plans.

Selection Notes

Select this component when a low pass filter with a 40 MHz cutoff is required in a 50 Ohm system. The KE1467 case style offers a connectorized solution for prototyping or fixed installations. Consider the insertion loss and return loss specifications provided in the electrical data sheet for signal integrity analysis. Ensure the power handling capabilities align with the input signal levels in the application circuit.

Part Context

This model belongs to the ZX75LP series of low pass filters from Mini-Circuits. The series includes various cutoff frequencies such as 105 MHz and 137 MHz, all sharing similar lumped LC construction and SMA connectivity. These components are widely used in RF and IF stages where harmonic suppression or band limiting is necessary. The series is known for consistent performance across the Mini-Circuits product line.

Replacement Considerations

Direct substitutes include other ZX75LP models with different cutoff frequencies if bandwidth requirements change. Verify mechanical compatibility of the SMA connectors and KE1467 footprint. Electrical parameters must be matched closely to maintain system performance.
