SLP-1200+

Overview

The SLP-1200+ is a coaxial low-pass filter manufactured by Mini-Circuits, designed for signal conditioning applications. It features a lumped LC architecture and operates within a frequency range of DC to 1000 MHz. The component provides a cutoff frequency of 1200 MHz with a 50-ohm impedance interface. It utilizes an SMA connector type and is housed in the FF99 case style. The device offers good attenuation rates, characterized by a typical 20dB/3dB bandwidth ratio of 1.35.

Feature Summary

• Lumped LC low-pass filter design for effective signal conditioning
• Rugged shielded case construction for durability
• SMA connector interface for standard RF integration

Applications

• RF signal filtering in communication systems
• Harmonic suppression in transmitter outputs
• Signal integrity maintenance in test and measurement equipment

Procurement Notes

Verify the specific suffix (+) indicates lead-free compliance when sourcing. Confirm the FF99 package style matches your PCB or fixture requirements. Ensure the SMA connector gender aligns with your system interconnects. Cross-reference the datasheet revision date to confirm electrical specifications have not changed. Validate environmental ratings against your operating conditions.

Selection Notes

Select this model when a sharp cutoff near 1200 MHz is required with minimal insertion loss below that threshold. The lumped LC topology suits compact designs where distributed elements are impractical. Consider the FF99 case dimensions for spatial constraints. Evaluate the attenuation rate if steep skirt performance is critical for adjacent channel rejection.

Part Context

This component belongs to Mini-Circuits' SLP series of coaxial low-pass filters. The series offers various cutoff frequencies to suit different RF bands. The SLP-1200+ specifically targets applications requiring filtering up to 1 GHz with a defined 1200 MHz cutoff point. It is part of a broader family of signal conditioning components.

Replacement Considerations

Consult Mini-Circuits documentation for direct equivalents within the SLP series. Verify that any substitute maintains the 50-ohm impedance and SMA interface. Check cutoff frequency and attenuation characteristics to ensure compatibility with the original design requirements.
