Fairview Microwave Inc. has launched a new line of phase locked oscillators that are accurate stable frequency sources and a key component for almost any communications, navigation, surveillance or test and measurement system. These PLOs are ideal for use in radar and other exciter or frequency generation applications, including phase locked loops, function generators, frequency synthesizers and local oscillator source in receiver and transmitter stages.

The 20 new PLO models are available with popular fixed output frequencies of 500, 1,000, 2,000, 4,000 and 6,000 MHz. Designs require an external frequency reference of either 10 MHz or 100 MHz and feature a TTL lock detect output to signal an out-of-lock condition. 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 dBc and -70 dBc respectively.

These devices are RoHS compliant and available in either compact surface mount or SMA connectorized packages. Surface mount packages feature gold over nickel mounting surfaces with downloadable Gerber file software for the mounting footprint. SMA connectorized packages are nickel-plated with DC bias and signal pins and an integrated mounting baseplate. All PLO models operate over the full temperature range of -30° C to +70° C and require a single positive DC voltage supply. Designs are built to be rugged and to withstand stringent MIL-STD-202 environmental test conditions for shock and vibration.

Fairview’s PLOs are in stock and ready for immediate shipment.
