RF/Microwave Variable Delay
- All In One Turnkey Solution
- Long Time Delay Up To ms
- Fast Change Up to 10 ns
- High Resolution Up To 20 bit
- High Frequency Up To 18 GHz
- Low Loss
The programable RPTD module 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. The RPTD 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. Photonwares offers several choices of non-mechanical switching; ultra-fast nano-second switching; and low loss MEMS switching. Integrated optical amplification compensates optical losses with delay-matching performance. The RPTD has a wide frequency range from 0.05GHz to 40GHz. The programmable delay module interfaces with a computer with user-friendly GUI through RS232, RS485, USB, GPIB, or Ethernet RJ45.
The RPTD platform 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.
