18GHz -40GHz Band Reject Filters-Specialised In Customised Production Of High Performance Rf Band Reject Filters
Characteristics and Application
18GHz -40GHz filters offer the following advantages:
1. high-frequency performance: capable of handling high-frequency signals up to 40GHz, suitable for high-end applications such as 5G communications, satellite communications, radar systems and so on.
2. high selectivity: provide excellent frequency selectivity, effectively separating the desired signal from interfering signals.
3. low insertion loss: low signal loss to ensure signal strength and quality.
4. high rejection performance: high rejection ability, reduce the impact of interference on system performance.
5. high Q: can provide a narrower bandwidth and better frequency selectivity.
6. temperature stability: suitable for use in variable environmental conditions.
7. wide bandwidth capability: support wider bandwidth to adapt to changing communication needs.

Nots
Filters to avoid coupling of input and output cables: When wiring, avoid bundling the input and output cables of the filters together to reduce the negative impact of electromagnetic coupling on the performance of the filters.
Maintenance and care of the filter: regular maintenance and inspection of the filter, especially when using electrolytic capacitors, need to pay attention to their life and regular replacement .
Avoid installing filters inside the shielding: installing filters inside the shielding may result in the EMI radiation generated by circuits and components inside the equipment being directly coupled to the outside of the equipment, thus reducing the shielding effect.
Atmospheric and environmental factors: Millimetre wave signals are more sensitive to atmospheric conditions, rainfall, fog and other atmospheric conditions may affect signal propagation and cause some degree of interference or attenuation.
