Digitally Controlled Attenuator, Modulator

Digitally Controlled Modulators

These models are digitally controlled attenuators or modulators. A 10 dB per volt control fuction is achived with an integrated hybrid linerizier. These units exhibit low insetion loss and are non-reflective
at all settings.
