The Low-Noise Rackmount Frequency Synthesizers from Quantic Wenzel can be customized to have a frequency range from 5 MHz to 18 GHz. They have options for low, ultra-low, and golden phase noise performance and phase locking with an external reference. The synthesizers include low-noise voltage regulators and can be mounted with crystal oscillator(s) and/or RF modules within the chassis. They deliver superior performance at a lower cost than a variable low noise frequency synthesizer with the flexibility of providing only the fixed frequencies needed for the requirement. These synthesizers are available in a 19″ rackmount Chassis (1U, 2U, 3U, and 5U options) and require an AC supply or specified DC supply. The frequency synthesizers are ideal for use in bench reference, radar test sets, and communication systems.
