Modular RF Distribution: FRM100 & DA-Series
Precision timing and frequency distribution are at the core of many modern systems—from RF test benches to telecommunications infrastructure. But as systems grow, so does the need for stable, scalable, and coherent clock sources.
At Esterline Research and Design, we provide modular signal solutions that enable engineers to scale their frequency distribution without sacrificing signal integrity. Our FRM100 Frequency Reference Module is an ultra-stable, embeddable frequency source derived from a high-precision OCXO, making it an ideal solution for applications that require a dependable, compact reference with two coherent outputs.
ERD's FRM100 Frequency Reference Module
However, in real-world applications, a single frequency reference often needs to be distributed to multiple subsystems. This is where our embeddable DA Series RF Distribution Amplifiers come into play.

Why Expand Beyond Two Outputs?
While the FRM100’s two configurable outputs are ideal for many applications, many systems require additional synchronized signals. Our DA Series amplifiers allow engineers to seamlessly expand and integrate these outputs into larger systems with diverse requirements.
Let's explore how our FRM100 module and DA series amplifiers work together to create flexible, scalable systems:
The block diagram above illustrates a practical application: one FRM100 module feeding into a 10MHz DA100 on one output and a 5MHz DA100 on the other. This configuration creates two sets of five synchronized outputs at 10MHz and 5MHz.
Need a Digital Output? Swap in DA300
Some applications require a CMOS clock signal instead of a sinewave output. In this case, the DA100 can be swapped for the DA300 CMOS Distribution Amplifier, providing a clean, fast-transitioning digital waveform.
This flexibility ensures that whether your system requires sinewave, CMOS, or a mix of both, our modular architecture adapts to your needs.
Our modular approach allows engineers to design frequency distribution systems that match their exact requirements—whether they need sinewave or CMOS outputs, high channel isolation, or scalable fan-out architectures.
