Pasternack Introduces Line of Free-Running Reference Oscillators

The oscillators are designed for phase locked loops, function generators, frequency synthesizers and receivers for communication, radar, navigation, surveillance and test and measurement applications. These free-running, fixed-tuned oscillators use a high-stability internal crystal reference as an integral part of the phase-locked assembly with a buffered amplifier output stage for improved ruggedness. The company says they provide a highly reliable single output frequency source and excellent performance with respect to temperature stability, induced noise and overall efficiency.

Pasternack’s six new free-running reference oscillators are available with single output frequencies of 10 MHz, 50 MHz or 100MHz. These designs offer a dependable frequency output with stability levels of +/- 5 ppm and are aging-rated at less than 1 ppm.  Additional performance features include an output power level of +7 dBm, phase noise as low as -150 dBc/Hz at 10 KHz offset and low spurious output of -70 dBc, according to the company.

These modules operate over the full temperature range of -30°C to +70°C and require a single positive DC voltage supply. They are available in either a compact SMA connectorized package with DC bias pins, or a true surface mount package outline that has a downloadable Gerber file for the mounting footprint.  These SMT and coaxial package designs are highly reliable and meet stringent MIL-STD-202 environmental test conditions for shock and vibration.
