LTCC (Low-Temperature Co-fired Ceramic) filters typically support a wide range of frequencies, depending on their design and application. Generally, they cover the following frequency ranges:

1. HF to Microwave Bands – LTCC filters commonly operate from a few MHz up to tens of GHz.

2. Common Ranges:

• Sub-6 GHz (100 MHz~6 GHz) – Widely used in wireless communications (e.g., Wi-Fi, 4G/5G, Bluetooth, GPS).
• Millimeter-Wave (24 GHz~100 GHz+) – Some advanced LTCC filters support 5G mmWave and automotive radar applications.

3. Specific Applications:

• Bluetooth/Wi-Fi (2.4 GHz, 5 GHz)
• Cellular (700 MHz~3.5 GHz for 4G/5G)
• GPS (1.2 GHz, 1.5 GHz)
• Automotive Radar (24 GHz,77 GHz,79 GHz)

LTCC technology allows for compact, high-performance filters with good thermal stability, making them suitable for RF and microwave systems. The exact frequency range depends on the material properties, resonator design, and manufacturing precision.
