MHM-2020 Active Hydrogen Maser
Microchip MHM-2020 has enhanced the unique Auto-Tune design of the MHM-2010 by re-engineering the electronics to attain even better stability.
Building on the world’s most widely deployed active hydrogen maser legacy, Microchip’s MHM-2020 enhances the exclusive Auto-Tune design of the MHM-2010 with redesigned electronics and software for superior stability.
It achieves daily drift rates < 3 × 10⁻¹⁶, along with greater environmental stability, and is designed for applications requiring extreme frequency stability and low phase noise.
Designed, built, and tested in the United States for reliable long-term operation, 95% of masers produced at Microchip’s dedicated facility since 1999 remain operational.
Each MHM-2020 is manufactured to rigorous quality standards and undergoes thorough performance verification testing before delivery.
