LFCN-2850+

Overview

The LFCN-2850+ is a low-pass filter from Mini-Circuits designed for RF applications. It operates with a cutoff frequency of 2850 MHz and maintains a 50 Ohm impedance. The device features an insertion loss of 1.5 dB and supports DC pass-through between input and output. It is housed in an FV1206 surface-mount package, suitable for board mounting. The component functions within a temperature range of -55°C to +100°C.

Feature Summary

• Provides effective low-pass filtering characteristics up to the specified cutoff frequency.
• Supports direct DC signal transmission between input and output ports.
• Constructed using LTCC technology for reliable performance in compact designs.

Applications

• RF front-end filtering in communication systems
• Harmonic suppression in transmitter circuits
• Signal conditioning in microwave modules

Procurement Notes

Verify the specific suffix requirements before ordering. The standard '+' suffix indicates lead-free construction compliant with RoHS standards. Confirm that the base model supports DC pass-through if isolation is not required. Ensure the PCB layout matches the manufacturer's recommended dimensions for the FV1206 package to maintain electrical integrity.

Selection Notes

Select this component when a low-pass response is needed up to 2.85 GHz with minimal insertion loss. Consider the LFCN-2850D+ variant if DC isolation to ground is necessary instead of DC pass-through. Evaluate the power handling capabilities against system requirements, as these filters are designed for specific power levels. Ensure the operating temperature range aligns with the environmental conditions of the target application.

Part Context

This part belongs to the LFCN series of LTCC low-pass filters manufactured by Mini-Circuits. These components are engineered for high performance in RF and microwave frequencies. The series offers various cutoff frequencies to suit different bandwidth requirements while maintaining consistent impedance and packaging styles for design flexibility.

Replacement Considerations

The LFCN-2850D+ serves as a functional substitute where DC isolation is required instead of DC pass-through. Verify that alternative parts match the 50 Ohm impedance and FV1206 footprint to ensure compatibility without redesigning the PCB layout.
