LFCV-2102+

Overview

The LFCV-2102+ is a miniature low-temperature co-fired ceramic (LTCC) surface-mount low pass filter designed for RF applications. It provides a DC to 21 GHz passband with a 50 Ohm impedance. Key electrical specifications include a typical insertion loss of 1.6 dB, a typical return loss of 16 dB in the passband, and a stopband rejection of 42 dB. The component supports a power handling capacity of 30 dBm and is compliant with RoHS and REACH standards.

Feature Summary

• Utilizes low-temperature co-fired ceramic (LTCC) technology for compact surface-mount integration
• Provides high stopband rejection to suppress unwanted harmonic frequencies
• Maintains low insertion loss within the designated passband range

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in transmitter output stages
• Frequency filtering in microwave test and measurement equipment

Procurement Notes

Verify the specific datasheet version for the LFCV-2102+ to confirm current manufacturing status and compliance certifications. Ensure that the required power handling and frequency specifications align with your system design before ordering. Check for any updated packaging or reel specifications if automated assembly is planned. Confirm availability through authorized Mini-Circuits distributors to guarantee genuine components.

Selection Notes

Select this component when a DC to 21 GHz low pass response is required in a small form factor. The LTCC construction offers robustness for surface-mount processes. Consider the 1.6 dB insertion loss and 42 dB stopband rejection against system noise floor and interference requirements. Verify that the 30 dBm power rating exceeds the maximum expected signal level in the application circuit.

Part Context

This part belongs to the LFCV series of LTCC low pass filters from Mini-Circuits. Similar models in the series, such as the LFCV-2002+ and LFCV-2202+, offer comparable DC-to-high-frequency performance with varying cutoff frequencies. These components are engineered for consistent performance across wide bandwidths while maintaining a miniature footprint suitable for dense PCB layouts.

Replacement Considerations

Direct replacements may include other Mini-Circuits LTCC low pass filters with similar cutoff frequencies, such as the LFCV-2002+ or LFCV-2202+. Verify that substitute parts match the 50 Ohm impedance and SMT termination style. Ensure the replacement maintains equivalent insertion loss and stopband rejection characteristics for the specific frequency band.
