ULP-40+

Overview

The ULP-40+ is a lumped LC low-pass filter manufactured by Mini-Circuits, designed for radio frequency applications. It operates over a bandwidth from DC to 40 MHz with a cutoff frequency of 56 MHz. The component features a 50 Ohm impedance and utilizes surface mount technology (SMT) within a compact top hat package measuring 0.25 inches by 0.25 inches. It provides an insertion loss of approximately 2 dB, ensuring efficient signal transmission within its specified passband while attenuating higher frequencies.

Feature Summary

• Utilizes lumped LC architecture for effective low-pass filtering characteristics
• Employing surface mount technology for automated PCB assembly compatibility
• Constructed in a compact top hat package to minimize board space consumption

Applications

• RF signal conditioning circuits requiring DC to 40 MHz passbands
• Harmonic suppression in low-frequency RF systems
• Interference filtering in communication equipment operating below 56 MHz

Procurement Notes

Verify the specific datasheet revision when sourcing, as Mini-Circuits may update electrical specifications or mechanical drawings over time. Confirm that the 50 Ohm impedance matches your system requirements. Ensure the SMT top hat package footprint aligns with your PCB design constraints before finalizing procurement decisions.

Selection Notes

Select this component when a sharp roll-off is not critical but cost-effective filtering is needed for frequencies up to 40 MHz. The lumped LC design offers a balance between performance and size. Consider the 2 dB insertion loss impact on overall link budget. This filter is suitable for general-purpose RF applications where standard attenuation characteristics are sufficient.

Part Context

Mini-Circuits is a global leader in RF, IF, and microwave components, offering products from DC to 86 GHz. The ULP-40+ belongs to their series of lumped element filters, which are distinct from distributed or LTCC technologies. These components are widely used in wireless communications and test equipment due to their reliability and standardized packaging formats.

FAQ

What is the physical package type of the ULP-40+?

The ULP-40+ is housed in a top hat package with dimensions of 0.25 inches by 0.25 inches, fabricated using surface mount technology.

Does the ULP-40+ support frequencies above 40 MHz?

The component is designed as a low-pass filter with a bandwidth up to 40 MHz and a cutoff frequency of 56 MHz, meaning it attenuates signals significantly above this range.
