Phase Locked Oscillators

Phase Locked Oscillators

A new line of phase locked oscillators (PLOs) deliver accurate and stable output frequencies with low phase noise and 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, and as a local oscillator source in receiver and transmitter stages. These 20 PLO models are offered with popular fixed output frequencies of 50, 100, 500, 1000, 2000, 4000, and 6000 Mhz. Typical performance 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. 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 are RoHS compliant and operate over the full temperature range of -30 to +70ºC. They require a single positive DC voltage supply 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.
