Demand for the transport of RF communications signals over Fiber Optic Links is rapidly increasing, driven by optoelectronic technology advances and the leverage of cost efficiencies of the optical telecommunications industry. Unlike coaxial cables, advances in fiber-optic technology now make it possible to transmit RF signals cleanly over extended distances without excessive insertion loss. Links with frequency coverage from 1 kHz to 50 GHz are supported, while maintaining extremely low noise figures, very high SFDR and extremely flat amplitude responses over frequency.
With this approach, it is possible to route Microwave/RF signals long distances, to remote locations, so that the receiver/processing hardware no longer has to be located within close proximity to the antenna. This also allows the receivers to be utilized in a pooled configuration serving multiple antennas, resulting in the potential for a smaller number of receivers for a multi-aperture system. By combining multiple antenna bands at light versus traditional RF combiners, a broadband feed can be formed that has no inter-modulation products at the band crossover points and only a slight (less than 1 db) degradation in noise figure. This provides the capability to tune a single receiver through a wideband optically mux’d signal derived from multiple narrower band antennas.
Finisar’s family of RF over Fiber products deliver the industries highest performance and can be optimized for very specific applications. Our complete product line includes compact modules, outdoor and wall mount units, as well as 1U and 3U modular, rack mount and custom systems. These products leverage Finisar’s world class laser and receiver product portfolios developed for ultra high-speed digital communications. Transmitters, Transceivers, and Transponders for Datacom and Telecom Applications are also available. These products are fully compliant with Ethernet, Fibre Channel, SONET/SDH/OTN and PON standards and operate at data rates up to 100 Gb/s. Finisar’s high-performance Analog, Datacom and Telecom products address the most challenging requirements of today’s modern networks.

Known for decades as innovators in instrumentation amplifiers, AR RF & MICROWAVE INSTRUMENTATION first introduced its “S” Series of amplifiers for customers needing highly linear broad band performance in the microwave spectrum. Until this design appeared on the market, customers were limited to the performance available only in “TWT” type amplifiers. Today AR RF & Microwave Instrumentation has delivered thousands of solid state microwave amplifiers and continues to launch new and innovative solid state products in these frequencies.
What's New with the “S” Series
Up to 1200 Watts of Solid State Microwave Power
A little while ago AR made the “S” series smaller and lighter, without losing any power. Now they've added more power without increasing size or weight. The 15-watt amp is now 20 watts. The 30-watt version is now 40 watts. And so on ... up to the 800-watt version, which is now 1200 watts.
Expandable Power
Many of AR's "S" Series amplifiers are designed so that when additional power is needed, you can add another amplifier, rather than having to toss out the old amp and start all over again with a higher power model. You can also use the amplifiers independently when higher power is not needed. AR calls this building block concept Subampability® and it's another way that AR products deliver more value and cost-effectiveness to customers.
Broader Frequencies
AR RF/Microwave Instrumentation has redesigned several of its "S" Series amplifiers to extend the bandwidth from 18 GHz down to 4 GHz. The models previously went down to 6 GHz. These redesigned amplifiers are:
Model 5S4G18 (5 watts CW, 4 - 18 GHz) (formerly model 5S6G18A)
Model 10S4G18 (10 watts CW, 4 - 18 GHz) (formerly model 10S6G18A)
Model 20S4G18 (20 watts CW, 4 - 18 GHz) (formerly model 20S6G18)
