Mini-Circuits SCLF-10.7+ Low Pass RF Filter with 14MHz Cutoff Frequency, 50-ohm

Product Specification

Functions

1. Low - pass filtering: It is mainly designed to allow signals with a frequency lower than the cutoff frequency to pass through smoothly while attenuating high - frequency interference signals above 14 MHz by up to 20 dB. This effectively filters out high - frequency noise mixed in low - frequency signals and ensures the purity of the target low - frequency signals.
2. Stable impedance matching: With a standard 50 - ohm impedance, the component can achieve good impedance matching with most radio - frequency (RF) and microwave system circuits. This minimizes signal reflection at the connection points, reduces signal loss during transmission, and improves the overall transmission efficiency of the system.
3. Wide temperature adaptability: It has a broad operating temperature range from - 40 °C to 85 °C. This enables the filter to maintain stable filtering performance in extreme environmental conditions, such as low - temperature outdoor equipment and high - temperature industrial control cabinets, without being affected by drastic temperature changes.
4. Low insertion loss: The insertion loss is only 3 dB. When the target low - frequency signals pass through the filter, the attenuation of signal strength is minimal, which ensures that the amplitude characteristics of the useful signals remain basically unchanged and guarantees the accuracy of subsequent signal processing.

Applications

1. RF communication equipment: It is applicable to low - frequency RF communication systems like short - wave communication devices and low - power walkie - talkies. It filters out high - frequency clutter generated by the communication circuit itself or external electromagnetic interference, so as to enhance the clarity of communication signals and reduce the bit error rate of signal transmission.
2. Industrial control systems: In industrial automation control systems, especially in equipment such as PLC (Programmable Logic Controller) and sensor data acquisition modules that transmit low - frequency analog signals, it can filter high - frequency interference from industrial sites (such as interference from frequency converters and motor starters). This ensures the stability and accuracy of data collection and control signal transmission.
3. Test and measurement instruments: It can be used as an auxiliary component in electronic measuring instruments such as oscilloscopes, signal generators, and spectrum analyzers. When testing low - frequency electronic components or circuits, it helps the instruments filter out external interference signals, allowing the instruments to obtain more accurate test data and ensuring the reliability of test results.
4. Consumer electronics: It is suitable for low - frequency signal processing modules in household electronic products, such as audio equipment, set - top boxes, and low - frequency remote control receivers. For example, in audio devices, it can filter high - frequency noise in audio signals, improving the sound quality of the equipment; in set - top boxes, it ensures the stability of low - frequency control signal transmission.
