GXSC Frequency Source SiP Precisely Meets Spectrum Source Requirements

A spectrum source is an electronic device used to generate various signals. It is an instrument capable of outputting highly stable, high-purity RF signals, used for calibrating spectrum analyzers and power meters, and widely applied in fields such as wireless communications, radar, and satellite navigation. Spectrum sources are indispensable tools in RF testing, and they come in various types, including tracking sources, noise signal sources, and general-purpose RF signal sources. Selecting the appropriate spectrum source allows for frequency response measurements, signal calibration, and system verification based on testing requirements.

 

The GXSC Frequency Source SiP operates in the 10GHz–20GHz range and integrates core modules such as RF IP cores, frequency synthesizers, power amplifiers, filters, and control units. By optimizing the packaging structure and interconnect design, it overcomes technical challenges such as high-frequency parasitic interference, signal attenuation, and insufficient integration. Its characteristics are highly suited to the high-frequency testing requirements of spectrum sources, making it an ideal component for such applications.

 

The GXSC frequency source SiP accepts a 100 MHz reference frequency and outputs 10 GHz and 20 GHz locked-phase signals with a 5 MHz step. It features excellent spurious suppression of ≥60 dBc and output phase noise of ≤-76 dBc/Hz at 100 Hz, ≤-89 dBc/Hz at 1 kHz, and ≤-92 dBc/Hz at 10 kHz, and ≤-92 dBc/Hz at 100 kHz, ensuring the purity of the spectrum source’s output signal and effectively enhancing the accuracy of weak signal detection and complex modulated signal analysis.
