Passive DAS

Rosenberger Mini-SMP connectors are extremely small coaxial connectors, approximately 70% of standard SMP size. They are designed for applications up to 65 GHz and mainly for high-speed signal transmission (typically 10 or 40 Gbps). Plugs are available as smooth bore-versions – for plug-in technology and backplane applications – and as vibration resistant full detent types, for the highest mechanical loads such as those found in aerospace engineering. Mini-SMP subminiature connectors are well-proven, offering a high level of flexibility in alignment tolerances and for simplifying the whole production process. Rosenberger Mini-SMP coaxial connectors are mateable with common Mini-SMP connectors as specified by MIL-STD-348A, Fig. 328, as well as GPPO™ (Gilbert Engineering Co., Inc.) and SSMP™ (Carlisle Interconnect Technologies) series. The PCB connectors are supplied in tape and reel packaging for automatic assembly to boards and also in blisters.

Rosenberger RPC-3.50 precision connectors, with an outer diameter of 3.50 mm, are air dielectric and include ruggedized versions. Their high specification ensures excellent performance in precision measurement microwave applications – over the full frequency range up to 26.5 GHz. They are intermateable with common 3.50 mm, SMA, K and RPC-2.92 connectors.

Rosenberger presents a new and innovative GPS over Fiber system for applications where coax cannot be used to route the GPS signal to base stations. With more centralized RAN and large-scale DAS applications, there are many cases where the GPS antennas are located too far from the base stations for coaxial losses to be acceptable. To overcome this issue, the GPS over Fiber system converts the RF signal to light, transmits it over the fiber, and then restores the light to the original RF signal. Working in contrast to the many systems that employ a bulky remote unit – which requires power and separate mounting space – as well as a large master unit encompassing an active GPS splitter, Rosenberger has rethought the process and designed a fiber-optic replacement for the coaxial cable. Instead of a master unit and a remote unit, the system uses an electrooptical converter (E/O converter) at the antenna and an opto-electrical converter (O/E converter) near the base station. By employing this method, the E/O converter becomes a small, compact unit that connects directly to the GPS antenna. The unit is so small that it can even fit within a 1 ½ inch pipe of the kind often used to mount GPS antennas. The O/E converter handles all alarms and is a compact unit. It can be used to power the E/O converter and can be connected to standard GPS splitters with full support for their redundancy functionality. This means that the GPS over Fiber system fully emulates the behavior of a passive copper cable and GPS antenna, allowing any device that is normally connected to the GPS antenna to maintain proper operation when connected to an O/E converter. Interconnecting the two units i.e. E/O converter to the O/E converter is a thin hybrid cable comprised of fiber and power, which means no power source is required at the GPS antenna. The individual link support for each GPS antenna allows for the flexibility of using a normal coaxial configuration and simply replacing each coax cable from a GPS antenna with an E/O converter, an O/E converter, and a hybrid cable. With a maximum hybrid cable length of 1.9 miles (3 km), this system can meet the demands of almost any installation

Rosenberger offers a wide test port portfolio of cable assemblies, ruggedized adaptors and an interchangeable port system for vector network analyzers (VNA) up to 90 GHz: Test port cables providing outstanding phase and amplitude stability are also available as sets containing two cables with a standard length of 60 cm each. The range is optimized for frequencies up to 12 GHz, 18 GHz, 26.5 GHz, 40 GHz, 50 GHz, 70 GHz and 90 GHz. VNA test port cables are also available as cable sets, containing two cables of 600 mm standard length, and are supplied in high-quality wooden boxes. Test port adaptors are designed to connect directly to the VNA test port via a ruggedized coupling nut. They are available in the RPC-3.50, RPC-2.92, RPC-2.40, RPC-1.85 and RPC-1.35 connector series. Available as "in series" and "inter series" versions, their ruggedized construction ensures reliable protection of VNA test ports and reduces mechanical abrasion to a minimum. Interchangeable port connectors are designed for test equipment applications using test ports that will be continually mated and re-mated. This has been achieved by the development of an interchangeable port connector system featuring a panel mounting half and an innovative neutral interface, allowing a high number of mating cycles without causing possible damage to the equipment device interface.
