RFComm provides a full range of state-of-the-art optical based RF delay solutions including fixed and variable delay lines with high precision& high RF input power handling capability; customer-defined fiber coil length selective delay; high resolution and fast digitally switching delay lines; turn-key optical or RF delay modules, we uniquely offer delay lines from few ns to ms large delay range, high time precision, and high variable resolution with both fiber loops for the long delay and dielectric medium for short delay.
These products are calibrated and tested for good performance. Our Strength is customized delay solutions.
The programmable delay line solution is a turn-key solution delivering unmatched performance in delay range, resolution, and reconfiguration speed. It converts an incoming RF signal into an optical signal and transmits through N fiber segments selectively, and re-coverts back into an output RF signal with variable time delay. Using optical switches, the time delay is variable and programmable with high resolution of 2 N delay selections.
This system allows for a long delay up to ms in a compact package with the superior temperature stability of fiber. Delay length and link performance requirements can be tailored over a range of performance levels to meet specific requirements. We offers several choices for delay selection. Integrated optical amplification compensates optical losses with delay-matching performance. The Solution has a wide frequency range from 0.05 GHz to 40 GHz. The programmable delay module interfaces with a computer with user-friendly GUI through various interfaces including Ethernet RJ45.
The Delay solutions includes a wide range fiber-optic transport solutions for satellite and microwave communications applications including, 5G networks, Radio Range Emulation, transparent inter- and intra-facility links, video transport, antenna remoting, Radar simulations, altimeter calibration, phased array antennas, Multi-path Fading, signal processing, electronic warfare systems and other high-dynamic-range applications.
