Low Phase: 3-30 dB

3 dB LOW PHASE ATTENUATORS
Low Phase attenuators features high resolution trimming over a 3 dB range with minimal change in phase length. These units also exhibit excellent flatness over their frequency ranges.
These units utilize a multi-turn, non-translating shaft with a locking device.
30 dB LOW PHASE ATTENUATORS
This line of continuously variable attenuators utilizes a unique approach to varying attenuation levels over a 30 dB dynamic range with little, if any change in phase length, Low Frequency sensitivity of attenuation is also maintained over the specified frequency range.
These units utilize a multi-turn, non-translating shaft with a locking device.
