Filters, Antenna filters
The short wave, but also other bands are affected by interferences. Some of these stem from natural processes, for example noise from thunderstorms or processes in the ionosphere, others are man-made disturbances. These are caused by nearby transmitters, by misaligned transmitter signals and also by overstrained receiver inputs.
In most cases, filters can be a great help here. A high frequency filter limits the bandwidth that is received, for example from the antenna to the receiver, or from the power amplifier to the antenna. In this way unnecessary components of the signal are filtered out. Modern SDR receivers implement the filter technology in the form of algorithms in the processor, but practice has shown that classical filters still offer many possibilities to improve reception.
Other filter technology is used to suppress interference from devices, for example in the case of direct radiation. Here WiMo offers a wide range of ferrites, which are not only used to build transformers, but can also be used as chokes to effectively prevent direct radiation.
