Overview
The LFCN-2852+ is an LTCC low pass filter manufactured by Mini-Circuits. It operates with a frequency range from DC to 28,500 MHz and features a 50Ω impedance rating. The component utilizes a surface mount FV1206-11 case style (1206 metric). Official specifications indicate an insertion loss of 1.9 dB at the passband and a cutoff frequency of 30.3 GHz.
Feature Summary
- Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for mm-wave frequency operation.
- Designed in a compact 1206 surface mount package for space-constrained applications.
- Provides high isolation characteristics suitable for RF signal conditioning.
Applications
- WiFi systems
- Bluetooth modules
- Zigbee networks
Procurement Notes
Verify the specific datasheet revision when sourcing, as electrical parameters such as insertion loss may vary slightly between documentation versions. Confirm the package marking matches the FV1206-11 designation to ensure compatibility with existing PCB footprints. Cross-reference the cutoff frequency specification against system requirements to validate performance margins.
Selection Notes
Select this component for designs requiring a low pass filter up to 28.5 GHz with minimal footprint. The 50Ω impedance aligns with standard RF transmission lines. Consider the LTCC construction for thermal stability. Ensure the application environment supports the specified operating temperature range defined in the manufacturer's data sheet.
Part Context
This part belongs to the LFCN series of LTCC low pass filters from Mini-Circuits. The series offers components with impedance ratings of 50Ω and frequency ranges extending up to 30,500 MHz. These filters are engineered for high-performance RF and microwave applications requiring precise signal filtering in small form factors.
Replacement Considerations
Consult official Mini-Circuits substitution guides for verified equivalents. Generic cross-references should be validated against impedance and frequency specifications before implementation.
