ULP-50+

Overview

The ULP-50+ is a lumped LC low-pass filter manufactured by Mini-Circuits, designed for RF signal conditioning applications. It operates with a DC to 50 MHz passband and features a cutoff frequency of 59 MHz. The component maintains a standard 50 Ohm impedance and utilizes SMD packaging in the QA2224 case style. Key electrical specifications include an insertion loss of 2 dB and attenuation values of 20 dB, 27 dB, and 47 dB at specific stopband frequencies. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides effective suppression of high-frequency harmonics and interference within RF circuits
• Utilizes compact surface-mount technology for integration into space-constrained designs
• Ensures stable signal integrity through precise impedance matching

Applications

• Wireless communication base stations
• RF test and measurement equipment
• Industrial measurement and control systems

Procurement Notes

Verify the exact datasheet version and electrical performance graphs directly from Mini-Circuits official documentation before finalizing design integration. Confirm that the QA2224 package dimensions align with your PCB footprint requirements. Ensure the specified operating temperature range meets your environmental conditions. Cross-reference the cutoff frequency and attenuation specs against your system's noise floor requirements.

Selection Notes

Select this component when a sharp roll-off below 60 MHz is required for 50 Ohm systems. Consider the lumped LC topology for cost-effective filtering in lower frequency bands. Evaluate the thermal performance within the -40°C to +85°C range if deployed in harsh environments. Compare insertion loss characteristics against alternative filter topologies to ensure signal fidelity meets system standards.

Part Context

This component belongs to Mini-Circuits' passive RF filter portfolio, specifically the ULP series of lumped LC filters. These devices are engineered for general-purpose RF signal conditioning, offering a balance between performance and physical size. The product line supports various frequency ranges, with the ULP-50+ targeting sub-100 MHz applications requiring reliable harmonic suppression.
