High Pass Filters
The TekBox High Pass Filters series provides critical signal conditioning for EMC pre-compliance and general RF testing applications. By effectively suppressing high-amplitude, low-frequency interference, these filters ensure that high-frequency signals of interest are captured with maximum clarity and precision. They are specifically engineered to reduce unwanted low-frequency noise that can often mask critical data or saturate sensitive measurement equipment during testing. Constructed with high-quality N-type connectors, these filters offer a robust solution for protecting spectrum analyzer inputs from damage or distortion caused by low-frequency overload. The high saturating current ratings, reaching up to 5.75 A in the TBHPF3-150kHz model, allow for reliable performance even in demanding power-related measurement environments. Their compact, inline design makes them easy to integrate into existing test setups without requiring additional mounting hardware or complex configurations. The product range includes several specialized models to cover various frequency bands and current requirements, ranging from the 9 kHz TBHPF1-9kHz-B to the wideband 3 GHz TBHPF1-150kHz-B. Other available options include the TBHPF2-150kHz covering up to 1 GHz and the TBHPF3-150kHz optimized for 135 kHz to 100 MHz. Each unit is designed for seamless connectivity between N-Male and N-Female ports, ensuring compatibility with standard RF cables, probes, and LISNs.Wide Frequency Coverage
Supports measurements from 9 kHz up to 3 GHz across various specialized models.
High Current Handling
Features saturating current ratings up to 5.75 A for demanding test applications.
Standard RF Connectors
Equipped with N-Male to N-Female connectors for easy inline integration into test setups.
Durable Metal Housing
Built with professional-grade materials to withstand frequent use in laboratory environments.
Advanced Receiver Overload Protection
These high pass filters are specifically designed to safeguard sensitive measurement equipment like spectrum analyzers and receivers from high-energy, low-frequency signals. By attenuating these unwanted components, the filters prevent input stage saturation and potential hardware damage during intense EMC testing sessions.
Optimized for Conducted Emissions Testing
Integrating these filters into an EMC test setup allows for more accurate analysis of high-frequency interference by removing dominant low-frequency noise. This is particularly useful when working with LISNs or other transducers where low-frequency power mains harmonics might otherwise obscure the high-frequency signals under investigation.
