In microwave and RF systems, the spectral purity and power stability of fixed-frequency local oscillator signals are critical indicators that determine receiver sensitivity, mixing efficiency, test accuracy and the overall link dynamic range. The YX-SM13315-M-N-L-1 is a fixed-frequency frequency synthesizer adopting PDRO architecture. It provides a precise fixed output frequency of 13.325GHz with a standard output power of -15dBm～-10dBm. It is a high-performance fixed-frequency frequency synthesizer designed for RF local oscillator drive and precision test scenarios that prioritize high signal purity without high power output.
PDRO stands for Phase-Locked Dielectric Resonator Oscillator. It adopts a hybrid design of high-Q dielectric resonator and sampling phase-locked loop, combining the ultra-low near-end and far-end phase noise advantages of dielectric oscillators with the high frequency stability and high-precision frequency locking characteristics of phase-locked loop technology. Unlike broadband frequency synthesizers optimized for wideband tuning, PDROs are specially tailored for single fixed-frequency operation, delivering cleaner spectrum, lower spurious emissions and better overall signal performance.
The YX-SM13315-M-N-L-1 operates at a fixed frequency of 13.325GHz with a low-power RF output of -15dBm to -10dBm. This low-level output eliminates the need for additional precision attenuation or power amplification circuits. The frequency synthesizer can be directly connected to mixer LO ports, receiver front-end drive links, RF test systems and calibration equipment, effectively simplifying system design and reducing test errors caused by extra link loss and device cascading.
