Quartzlock Products


The Quartzlock A5-8 Distribution Amplifier is a precision distribution amplifier for use with Frequency Standards or other signals where a need for multiple outputs from a single generator is required.
Available in 8 outputs. The A5-8 replaces previous A5 models; the specification has improved
isolation and other parametrics.

High Isolation between inputs and outputs
Ultra low phase noise
Ultra high stability
Very low harmonic distortion
Bipolar Junction Amplifiers 24Vdc BBU &/or 90 ... 240Vac operation

Hydrogen Maser compatible performance
Retains original input signal characteristics
8 outputs
May be supplied with two or three channel inputs
No cross channel interference between outputs for mission critical applications

Frequency Distribution where the highest levels of stability and lowest levels of phase noise are required
