Fairview Microwave's USB-controlled, phase locked loop (PLL) frequency synthesizers

Fairview Microwave introduces USB-Controlled PLL synthesizers for test and measurement applications

  • Fairview Microwave has launched a line of USB-controlled, phase locked loop (PLL) frequency synthesizers.
  • Six new USB-controlled PLL frequency synthesizers are designed for test and measurement applications. Each model is ready to ship with accessory cables and command control software.
  • Housed in compact coaxial packages, theses synthetizer cover bandwidths ranging from 25 MHz to 27 GHz.

These PLL synthesizers are designed for applications that involve electronic warfare, signal generators, benchtop test and measurement and microwave radios.

Fairview’s six new PLL frequency synthesizer models are compact, rugged, SMA-connectorized designs that support USB 2.0 interface with a PC computer supplying DC power and GUI command control.

They cover a range of frequency bands from 25 MHz to 27 GHz. These models deliver output attenuation that is adjustable up to 50 dB in 1 dB steps and output power levels ranging from +10 dBm to +19 dBm typical. Phase noise is as low as -108 dBc/Hz at 100 MHz offset and phase locked speed is 1 msec typical.

These synthesizer models also feature a 50 MHz internal frequency source and optional external reference with supplied cable. Frequency resolution can be adjusted using either integer (default) or fractional modes with resolution to a step size down to 1 MHz. Modules support RF power disable, phase locking and unlocking, and functional LED indicators that confirm a USB connection.

These PLL frequency synthesizers are RoHS and Reach compliant and are classified as EAR99. An user manual and VISA compliant software package can be downloaded from the Fairview website.
