IRVINE, Calif. – Pasternack in Irvine, Calif., is introducing a line of USB-controlled phase locked loop, PLL frequency synthesizers for military RF and microwave applications in electronic warfare (EW), microwave radios, signal generators, and benchtop test and measurement.
RF and microwave communications systems where signal integrity is of prime importance rely on PLL synthesizers fir high levels of frequency stability and accuracy with phase noise characteristics that enable components in the signal chain to perform at their optimum levels.
These PLL synthesizers can be useful in applications involving signal generators, benchtop test and measurement, electronic warfare, and microwave radios.
Pasternack's six models of PLL frequency synthesizers cover 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 millisecond 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 user manual and VISA compliant software package can be downloaded from the Pasternack Website.
