Pasternack, a leading provider of RF, microwave and millimeter wave products, has launched a new line of USB-controlled Phase Locked Loop (PLL) frequency synthesizers.  In RF & Microwave communications systems where signal integrity is of prime importance, PLL synthesizers offer high levels of frequency stability and accuracy with exceptional phase noise characteristics that allows components in the signal chain to perform at their optimum levels. These new PLL synthesizers can be useful in applications involving signal generators, benchtop test and measurement, electronic warfare, and microwave radios.

Pasternack’s six new models of PLL frequency synthesizers cover a broad range of frequency bands from 25 MHz to 27 GHz.  The compact and rugged SMA-connectorized designs support a USB 2.0 interface with a PC computer that supplies DC power and GUI command control.  Models offer high output power levels that range from +10 dBm to +19 dBm typical, and output attenuation is adjustable up to 50 dB in 1 dB steps. Phase locked speed is 1 msec typical and phase noise is as low as -108 dBc/Hz at 100 MHz offset.

Additional features include 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 functional LED indicators that confirm a USB connection, phase locking and unlocking, and RF power disable.  All models are RoHS and Reach compliant and are classified as EAR99. A comprehensive user manual and VISA compliant software package can be downloaded from the Pasternack website. 

“Pasternack’s six new models of USB-controlled PLL Frequency Synthesizers offer a wealth of desirable features for designers and are ideal for test and measurement applications.  Each model comes complete with accessory cables, downloadable user manual and command control software that’s ready to ship direct from stock with no MOQ,” said Tim Galla, Active Component Product Manager at Pasternack.
