| Part Number | LFCN-4400+ |
| Manufacturer | Mini-Circuits |
| Category | RF Components > RF Filters > Multilayer Ceramic Low Pass Filter |
| Description | 50Ohm SMD Low Pass Filter, DC~5290MHz Cutoff Frequency, RF Harmonic & Spurious Noise Suppression,SMD-4P,3.2×1.6mm Package |
Product Overview
The LFCN-4400+ is a compact surface-mount low-pass RF filter developed by Mini-Circuits with a 5290MHz cutoff frequency. Built with advanced multilayer ceramic dielectric technology, this component maintains low insertion loss across full DC to 5290MHz passband and provides outstanding high-frequency stopband attenuation to suppress PA harmonics, local oscillator spurious emissions and unwanted out-of-band interference. Mini SMD footprint supports fully automated SMT pick-and-place production and ensures stable electrical performance across a wide working temperature range. It is widely implemented for front-end signal filtering, output harmonic cancellation and signal purification in broadband microwave modules, 5G sub-6GHz circuits and high-frequency laboratory RF test equipment.
