Fast Switching Direct Synthesizers
CAES' RF microwave series of fast switching direct synthesizers have been designed for use in commercial systems and military systems where demanding performance, high reliability and fast switching are critical.
With switching speeds from 250 nanosecond, the DS delivers ample speed to meet the required response times of EW Simulator, Radar, RCS, ATE and Antenna measurement systems. In addition, the 1 Hz step size capability allows the frequency to be controlled to a high precision.
Custom versions are available with different step sizes and bandwidths. Parallel programming is standard in order to optimize speed. Other interfaces are available as options.
This family of direct synthesizers has been designed for low power consumption and high reliability.
The complete DS synthesizer, with its combination of advanced performance features, is housed in a low profile 5.25” high rack- mountable chassis or optional 1.75” or 3.5” chassis for some models. For specialized applications the DS can be tailored to suit custom bands and physical outlines due to its modular architecture. The touch screen front panel version provides simple control and versatility. SatCom and digital radio equipment, as well as in high-performance frequency agile surveillance, radar and communications equipment.
Our optional coherent switching synthesizer, unlike other technologies available, can perform coherent switching down to 1 Hz of the synthesizer. Previous to this breakthrough, coherent resolutions have been limited to larger steps because switching time performance degraded as resolution is decreased. This design from CAES overcomes this limitation and provides a new tool for Signature Measurement Technologists.
This new synthesizer can be ordered with many options and can be custom configured to meet your requirements. As an example, an FM modulator can be added to the coherent unit to make it interchangeable between Simulator and Signature Measurement applications.
