Low Noise PLOs
Operating at fixed frequencies in the 300 MHz to 22 GHz range, the APL-02 series of fundamental frequency phase-locked oscillators provides a low noise and stable local oscillator input for frequency converters for multiple uses. The compact oscillators are either coaxial resonator based for frequencies up to 3.0 GHz, using low noise silicon bipolar active devices or dielectric resonator based for frequencies above 3.0 GHz, using GaAs FETs or MMICs. The use of fundamental frequency architecture drives down phase noise and minimizes physical size. For example, a 4 GHz unit achieves considerably better than –110 dBc/Hz phase noise at 10 kHz offset from the carrier with a typical floor close to –140 dBc/Hz. Using an internal reference the “close in” phase noise is better that –64 dBc/Hz at 100 Hz offset and can be improved further by the use of an external ultra low phase noise OCXO reference.
