The Phase Matrix model PLS-4900-Q10E is a high performance, low noise, 4.9 GHz phase-locked oscillator (PLO). The design of this PLO’s primary source consists of a low-noise, bipolar-silicon-transistor oscillator. In addition, a buffer amplifier in the output path provides the desired power output and load isolation. Power output is 17 dBm (typical) into a 50 ohm load. Phase noise at 10 kHz and 100 kHz offsets is -110 dBc/Hz and -130 dBc/Hz respectively. The PLS-4900-Q10E requires a 10 MHz external reference oscillator and is housed in a compact (4.5" x 2.25" x 0.63") connectorized package.
