* To change calibration frequency add desired frequency after the model number as shown in the following example: 159–600B–dB–2–2 becomes: 159–600B–dB–2–2/5.1 when a calibaration frequency of 5.1 (GHz) is desired.


Ordering Information

The Model numbers listed above are the most common model numbers for size, material, flanges ** , and calibration, however, these models can easily be altered to accommodate customer needs by following the Model # code system shown below.  In addition the customer must choose the attenuation value appropriate for application (3dB, 6dB, 10dB, 20dB, or 30dB) and insert it in the model number where dB is listed.

** See ATM Flange page for more information on flanges.

                Typical Part #:             WGSize – 600 – Material – dB value – Flange1 – Flange2
