The Variable RF-Photonic Time Delay system (RPTD) is an all-in-one turn-key unit that provides true-time delay with convenient RF input/output without the need for pre or post-RF amplifiers. Perfected over 15 years, it uniquely features a long delay of up to ms, low (ms) to ultra-fast (ns) delay variation speed, up to 25 bits high resolution, and high RF frequency of up to 40 GHz. Internally, the RF signal is converted to an optical signal and transmitted over a fiber optic link to the receiver, where it converts back to an RF signal. Signal delay time can be digitally varied by switching to pass through N fiber segments, therefore providing N-bit resolution. Delay length and link performance can be tailored to meet customer-specific requirements with great flexibility. Our unique optic amplifiers with short intrinsic delay are used in this unit to compensate for loss through long fiber loop segments and switches. The system has the reliability function of built-in temperature sensors and checking the switchable delay segments. USB/GUI or RS232 interface is a standard, while high-speed switching is controlled by TTL through a D connector. A front touchscreen display is also an option. The system delivers unmatched performance for radar testing, signal processing, phased array antennas, and phase noise testing with greater flexibility than traditional coax or waveguide solutions
