LTCC High-Pass Filter with 13.3 GHz Cutoff Frequency, 50-ohm Impedance, and Low

Product Specification

Functions

1. High-pass filtering with fixed cutoff frequency: As an LTCC (Low Temperature Co-fired Ceramic) high-pass filter, it has a cutoff frequency of 13.3 GHz. It can smoothly pass high-frequency signals in the 14300 - 18500 MHz range while effectively attenuating low-frequency interference signals below the cutoff frequency, which is crucial for ensuring the purity of target high-frequency signals.
2. Standard 50-ohm impedance for good matching: It is designed with a standard 50-ohm impedance, which can achieve excellent impedance matching with most radio frequency and microwave circuit systems. This minimizes signal reflection at the connection ports, reduces signal loss during transmission, and improves the overall signal transmission efficiency of the system.
3. Low insertion loss to maintain signal integrity: The filter has an insertion loss of 2.8 dB. When high-frequency signals pass through it, the attenuation of signal strength is small. This advantage can well preserve the amplitude characteristics and integrity of useful high-frequency signals, laying a solid foundation for the accuracy of subsequent signal processing.
4. Compact SMD package for integrated installation: Adopting the 1206 surface - mount device package specification, it has a compact size of 3.2 mm × 1.6 mm × 1.04 mm. This compact structure makes it suitable for being installed on printed circuit boards with dense layouts, meeting the miniaturization and integration design requirements of modern electronic products.

Applications

1. RF and microwave communication systems: It is applicable to high-frequency communication fields such as 5G communication modules and satellite communication equipment. It can filter out low-frequency clutter in high-frequency communication signals, improve the signal-to-noise ratio of communication links, and thus enhance the stability and reliability of long-distance and high-speed signal transmission.
2. High-frequency electronic measuring instruments: It can be used as an auxiliary component in high-frequency test instruments like vector network analyzers and high-frequency signal detectors. When testing high-frequency circuits or components, it helps the instruments eliminate low-frequency noise interference from the external environment and internal circuits, enabling the instruments to obtain more accurate test data.
3. Aerospace electronic equipment: In aerospace electronic systems that need to process high-frequency signals, this filter can play a role in optimizing signal quality. It can resist low-frequency interference from complex aerospace environments and internal equipment of aircraft, ensuring the normal transmission of high-frequency signals in key systems such as on-board communication and navigation, and improving the operational stability of the equipment.
4. Miniaturized high-frequency consumer electronics: It is suitable for high-frequency signal processing modules in miniaturized electronic products such as high-performance wireless routers and microwave sensors. Its small size and stable filtering performance can meet the requirements of these products for high-frequency signal processing, helping to improve their overall working performance.
