Intermodulation filter IMF8-1V-50S-R/2(X/2), installed in transmitting section, will provide low loss signal passage, attenuate out-of-band transmitters radiation, preventing signals induced to antenna from penetration to transmitter output stage. Single isolator in this filter can be used, when distance between neighboring antennas does not exceed 10 λ across or exceed 2 λ at coaxial vertical arrangement of antennas. For short distances IMF8-1V-50D with double isolator must be used.
The ferrite isolators of Regular (R) class provide an operation of the intermodulations filters or transmitting link in temporal regime of exploitation with TX/RX =1:5, i.e. when the working load onto the transmitters of your system is not high.
The ferrite valves of Extreme (X) class are being applied in the case when repeaters operate with enhanced load (up to 100% of the cycle). These are more expansive and highly reliable products with the valves based upon the radiators (which do not allow the ferrites to become overheated) and for massive carrying out (external) loads.
