Interference Mitigation Filters
The densification of radio spectrum has led to an increasing need for interference mitigation solutions.
Interference suppression filters provide a simple, cost effective and low loss solution for minimising spectral emissions and attenuating interference signals preventing them from limiting receiver performance whilst retaining the maximum use of the spectrum available.
The ever increasing demand for data has led to the need for more spectrum. This has been provided by re-farming of existing frequencies and the release of new spectrum though the Digital Dividend and other additional blocks. These changes have led to some interference problems between networks and with other RF systems. Many of the new blocks are small and close to other blocks so to mitigate any interference and blocking signals, Filtronic has designed filters that provide rejection with the smallest possible loss of usable spectrum and minimal impact on the signal characteristics.
Filtronic solutions are designed to be easy to install into the network and can be mounted on walls, poles, inside cabinets or even within a pole and size and weight are kept to a minimum. Interfrence and blocking protection can be designed as a stand alone unit or integrated into other filtering or combining depending on the application. Other options include field reconfigurable filters, switchable filters and DC and AISG passthrough to the antenna from the base-station. Some example of our products and solutions include:
- UMTS 900/ GSMR
- LTE2600 FDD/TDD
- LTE800/ ATG
- LTE800/ SMR
- LTE2600 / Radar
- LTE800/ DTV
- GSM-R / EGSM
