Brief Description The multicouplers of the R&S®ATCMC family are specifically designed for the use in ATC receiving systems and they match with the ATC receivers from Rohde?&?Schwarz. The space-saving R&S®ATCMC8 optimally supports typical ATC system installations with eight receivers operated in parallel on one antenna. The R&S®ATCMC16 features simultaneous signal distribution to up to 16 receivers.
Features & Benefits Suppression of adjacent high-power signals The integrated bandpass filtering of the ATCMC considerably improves the reception conditions for the connected receivers. Distortion signals such as high-power FM signals in the VHF band or TV signals in the UHF band are suppressed. To offer optimized filtering for any application, the R&S®ATCMC is available as either a VHF or a UHF model. Rohde&Schwarz also offers various R&S®ATCMC options with different filter characteristics. Available as 1-to-8 or 1-to-16 model For space and cost reasons, parallel operation of up to eight or 16 receivers on a single antenna is very common in air traffic control. The R&S®ATCMC multicoupler family can easily handle this challenge and is therefore available as either an 8-port or 16-port model. To prevent the connected receivers from affecting each other (e.g. due to local oscillators and synthesizers), both models feature high port-to-port isolation. Integrated automatic emergency power switchover The R&S®ATCMC is ideal for operation with either AC or DC power. The integrated electronic switchover mechanism detects interruptions in the AC power supply and immediately switches automatically to the DC supply. The 24 V DC emergency power supply systems that are common in ATC can be used. Reliable protection against large signals Special importance was placed on the linearity (IP3) and the large-signal immunity of the ATC multicoupler. The integrated protective circuits at the RF input of the R&S®ATCMC reliably prevent large signals from damaging the connected receivers. Remote monitoring through floating alarm contact Featuring an integrated alarm contact as standard, the R&S®ATCMC multicoupler family offers impressive capabilities for remotely monitoring the internal operating state. If a malfunction occurs, the R&S®ATCMC immediately switches the floating contacts of a relay to indicate the modified operating state. All internal supply voltages of the amplifiers are monitored. This provides the opportunity to use an external Web I/O interface to evaluate the signalized status via simple network management protocol (SNMP). In conjunction with Rohde&Schwarz Series4200 radios, this alarm contact makes it possible to automatically report the operating state of the R&S®ATCMC to the user.''
