VHF/UHF circulator for the R&S®Series4200 radios. ATC radio stations with multiple, simultaneously operated transmitters can be subject to unwanted cross-interference which can cause transmitters to reduce their output power. There is also a risk that signal intermodulation products will impair radio communications. The R&S®KR420 circulator frame and the R&S®KR420-Z1 circulator module were developed to reduce such interference.
The R&S®KR420-Z1 circulator module was designed for the R&S®Series4200 radios. It consists of a VHF/UHF double circulator unit with integrated terminations and an optional VSWR meter. The module attenuates reflected signals from the antenna to the transmitter by up to 50 dB to ensure smooth radio communications. The actual transmit signal remains practically unattenuated.
- Up to ten circulator modules accommodated in a 3 HU 19" frame
- 40 dB to 50 dB attenuation of reflected signals
- 50 ohm termination for power levels up to 50W
- Optional VSWR meter
- For use with the R&S®Series4200 radios in R&S®KG4200 ATC system racks
