Characteristics of Shunluo LTCC products

Shunluo's LTCC products are mainly composed of microwave ceramics and high conductivity metal conductors, which are co fired at lower temperatures (1000 ℃). They have low cost, high reliability, excellent high-frequency high-speed transmission, and wide passband characteristics, making them suitable for use in RF communication circuits. As is well known, RF communication circuits are developing towards modularity, miniaturization, and higher reliability, and Shunluo LTCC products are also actively improving to meet the new requirements of RF circuits.

Modularization

Affected by the core technology features of 5G, the number of internal RF devices in mobile phones is constantly increasing. With the increase of frequency bands and the application of carrier aggregation, separated RF devices are no longer able to meet the requirements. In order to meet the consumption needs of intelligent mobile terminals, the modular development of RF devices has become a trend.

1. Solve the RF complexity challenges brought by multi frequency bands;

2. Reduce the volume of RF components;

3. Provide a global carrier aggregation modular platform, etc.

LTCC devices can support complex designs with more internal components and stronger functions, making them more adaptable to the development trend of integrated modules.

Miniaturization

Low Backing:The miniaturization of mobile phones and modules requires further miniaturization of devices, as well as further reduction in height.

Bottom electrode:The density of PCB components is increasing, and LTCC products are changing from side electrodes to bottom electrodes.

High performance materials

The development of integrated, multifunctional, and thin electronic ceramic components has put forward a series of new requirements for electronic ceramic materials, such as material refinement, material multifunctional, high-frequency, and low loss. The key technical issues that need to be addressed in the development of electronic ceramic materials in the coming years include the following aspects.

1. Low lossUltra low loss dielectric ceramic materials suitable for key microwave components in low energy wireless/mobile information systems, such as nanocrystalline material preparation, ultra-thin ceramic film forming, etc., are new electronic ceramic materials and key technologies that meet the miniaturization/miniaturization of electronic components.

2. High frequency:With the development of 5G/6G technology, the communication frequency band is gradually advancing from microwave to millimeter wave, and the demand for new electronic ceramics, especially ceramic dielectric materials, that adapt to higher frequency bands will sharply increase.

3. More materials co fired:New functional electronic ceramic materials for multifunctional electronic information systems.A new multifunctional ceramic material system with electrical, magnetic, optical, thermal coupling behavior and extraordinary electromagnetic characteristics, used for passive component integration and noNew electronic ceramic materials with source active integration and modularization.

4. High reliability:New information functional ceramic materials that work under complex external fields or extreme environmental conditions, have stability and excellent service behavior.
