HV Measurements

Rosenberger’s new RPC-1.35* precision connector series meets the growing demand for precision, high-performance RF-connections up to 90 GHz. The range addresses the expanding market for 5G, industrial sensors in the E-Band, millimeter wave sensors for self-driving vehicles, WLAN IEEE 802.11ax and 802.11ay. RPC-1.35 connectors offer a highly robust mechanical design, minimum 3000 mating cycles, high connector repeatability, and maximum return loss values – ideal for ensuring RF measurements in the E-Band without delays. The product portfolio covers semi-rigid and flexible cable assemblies, PCB connectors, test PCBs, cable connectors, in-series and inter-series adaptors, test ports, floating and waveguide-to-coaxial adaptors as well as gauge and calibration kits. *A working group, comprising PTB (Physikalisch Technische Bundesanstalt), Rosenberger, Rohde & Schwarz and Spinner, designed the new 1.35 mm connector to close the gap between 1.85 mm and 1.00 mm connectors. The interface standardization is in progress.

Rosenberger RPC-1.85 precision connectors – with 50 Ω impedance and 1.85 mm outer conductor diameter – are designed for test & measurement applications up to 70 GHz. Delivering outstanding reliability and repeatability performance they are intermateable with common 1.85 mm series and V connectors as well as with RPC-2.40 connectors. This comprehensive product range is suitable for semi-rigid cables and microwave components and includes cable, panel and PCB connectors, adaptors and test & measurement accessories – including RPC-1.85 calibration kits, cables assemblies, measurement equipment, attenuators, sliding loads and airlines.

Rosenberger RPC-2.40 connectors – high reliability and outstanding repeatability – are designed for precision test & measurement applications up to 50 GHz. With 50 Ω impedance and 2.40 mm outer conductor, they are intermateable with many other 2.40 mm series connectors such as APC-2.40, OS-50, HP-2.40 or RPC-1.85 and V connectors. A wide range of RPC-2.40 cable and PCB connectors, adaptors and interchangeable port connectors is available as well as test & measurement accessories. These include RPC-2.40 calibration kits, test cables and measurement equipment.

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
