Frequency Synthesizer

We offer high-performance synthesizers based on our own high-precision, low-jitter, low-noise crystal oscillators.
By adopting our own oscillator, we can flexibly accommodate customized design and propose the most suitable synthesizer for your application.
We also apply our proprietary digital signal processing technology to achieve high-speed frequency switching, fine frequency setting, low spurious and low noise.
We have obtained JIS Q 9100 certified in 2021 and will contribute to a wide range of fields from civilian to aerospace and defense markets by supplying high-quality and highly reliable products that comply with aerospace and defense quality management.
