The R&S®HS9043 cavity antenna filters are proven “workhorses” that have been used successfully for decades. They are used in single-channel systems where medium power handling capacity and medium selectivity are sufficient. The filters make it possible to set up radiocommunications systems where radios can be simultaneously operated in very tight spaces.

R&S®Series4200 detection of simultaneous transmissions (DSiT) option for air traffic control

ATC radio stations with multiple, simultaneously operated transmitters can be subject to unwanted interference which can cause transmitters to reduce their output power. There is also a risk that signal intermodulation products will impair radiocommunications. The R&S®KR420 circulator frame and the R&S®KR420-Z1 circulator module were developed to reduce such interference.
