Pasternack has unveiled a new line of phase-locked oscillators (PLO) that deliver accurate and stable output frequencies with low phase noise and good spurious performance, making them ideal for use in radar and other exciter or frequency-generation applications. Typical applications include phase-locked loops, frequency synthesizers, function generators or a local oscillator in receiver and transmitter stages.
Pasternack’s 20 new phase-locked oscillator models are offered with popular, fixed output frequencies of 50, 100, 500, 1000, 2000, 4000 and 6000 MHz. Typical performance for these PLOs includes excellent phase noise of −105 dBc/Hz at 10 kHz offset, a buffered output power level of +7 dBm and low second-harmonic and spurious-suppression levels of −25 and −70 dBc respectively. They require an external frequency reference of either 10 or 100 MHz and feature a TTL lock-detect output to signal an out-of-lock condition.
These phase-locked oscillator models require a single, positive, DC voltage supply and operate over the full temperature range of −30°C to +70°C. They are RoHS compliant and are available in either SMA-connectorized or compact surface-mount packages. SMA-connectorized packages are nickel-plated with DC bias and signal pins and an integrated mounting baseplate. Surface-mount packages feature gold-over-nickel mounting surfaces with downloadable Gerber file software for the mounting footprint. The PLOs are built to be rugged and withstand stringent MIL-STD-202 environmental test conditions for shock and vibration.
Pasternack’s phase locked oscillators are in stock and ready for immediate shipment with no minimum order quantity.
Tim Galla, product manager, said “Our new, comprehensive line of phase-locked oscillators provides designers with a variety of popular fixed output frequencies that are stable and accurate. These 20 innovative designs are key components for many navigation, surveillance, communication or test and measurement systems.”
