A new name and new direction
Since 1986 ACT – formerly Advanced Crystal Technology – have evolved into a leading design partner for high-performance frequency control products.

Custom frequency solutions through new partnerships
Our partnership with Esterline Research and Design (ERD) enables us to push the boundaries of high-precision oscillator technology. These breakthrough products set new standards for TCXOs and OCXOs, creating the highest-performance and most accurate oscillator technology in the marketplace today.

A wide range of standard frequency products
We also have a robust frequency control product portfolio, including crystals, clock oscillators, TCXOs and filters.
