UHF* coaxial connectors with geared screw locking frontal interlocking teeth and without defined impedance are intended for very low frequency applications up to 300 MHz. They are intermateable with “banana” connectors. *UHF = Ultra High Frequency, when developed in the 1930s, in fact today even wrong.

Rosenberger desktop analyzers are portable and flexible for R&D and test labs. The budget friendly broadband base unit concept offers maximum flexibility to add any other filter unit in the range of 700 to 2700 MHz to the base unit. It allows continuous flexibility in an ever changing environment.

Rosenberger’s comprehensive portfolio of cost-effective, high-quality and precision products enables a broad spectrum of industrial test & measurement applications for active or passive devices. While several types of network analyzers (NAs) have become increasingly important in the development of microwave circuits and systems in industrial measurement applications, vector network analyzers (VNAs) are particularly useful. This is due to their calibration capability and the ability to measure more parameters. Rosenberger develops and offers a wide range of metrology kits for a variety of standard and precision interfaces when performing calibration, verification and traceability, as well as gauges and gauge kits for vector network analyzers (VNAs).

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
