1.High-Frequency Component Integration
LTCC technology enables high-density integration of passive components operating in high-frequency ranges (10 MHz to terahertz bands) through multilayer ceramic structures and silver conductor printing processes, including:
2.Filters: Novel LTCC multilayer bandpass filters, utilizing lumped-parameter design and low-temperature co-firing (800–900°C), are critical for 5G base stations and smartphones, effectively suppressing out-of-band interference and enhancing signal purity. Millimeter-wave folded end-coupled filters improve stopband rejection and reduce circuit size via cross-coupling and 3D embedded structures, meeting radar and satellite communication requirements
3.Antennas & Power Dividers: Low dielectric constant materials (ε<sub>r</sub> =5–10) combined with high-precision silver paste printing support the fabrication of high-Q antennas, couplers, and power dividers, optimizing RF front-end performance
Core Applications in 5G Communications
1.5G Base Stations & Terminals: LTCC filters, with advantages of compact size, wide bandwidth, and high reliability, have become mainstream solutions for 5G Sub-6GHz and millimeter-wave bands, replacing traditional SAW/BAW filters
2.RF Front-End Modules: Integration of passive components (LC filters, duplexers, baluns) with active chips (e.g., power amplifiers) into compact SiP modules reduces signal loss and improves system efficiency
3.Technical Advantages Driving Innovation
High-Frequency & Thermal Performance: Low dielectric loss (tanδ <0.002) and superior thermal conductivity (2–3 W/m·K) ensure stable high-frequency signal transmission and enhanced thermal management for high-power applications57.
3D Integration Capability: Multilayer substrates with embedded passive components (capacitors, inductors) reduce surface-mount requirements, achieving >50% circuit volume reduction
