Applications of a micro-cavity LTE filter

Description: 

Undoubtedly, we all know that the signals LTE/4G are just around the corner, occupying the last part of the UHF band.
To mitigate interference on the TV channels that are in their vicinity, Televes has developped a range of filters called “LTE”. These filters are based on micro-cavity techniology, which consists of a series of cavities that are magnetically coupled together; as a consequence, this

 

type of filter confines it’s magnetic  fields in cavities that results in very little coupling losses as well as excellent values of rejection band.
By using these filters the TV channel 60 can be virtually isolated from the LTE/4G Downlink band, with barely 0.5 dB insertion loss for its passband.
Any other type of filter would cause that the headend might not be able to equalize the signals received; usually due to the risk of saturation caused by the rest of signals coming from the antenna
