The CHT4016-QEG the new 4-14GHz attenuator
A new 4-14GHz attenuator


The CHT4016-QEG is a 4-14GHz 6-bit digital attenuator designed to provide a dynamic range of 31.5dB in 0.5dB steps.   

The CHT4016-QEG features the following market leading performances:

•    an excellent amplitude accuracy with 0.2dB of RMS attenuation error,
•    a very good return loss of -14dB,
•    a very low RMS phase variation of 6°,
•    digital control interface.

This circuit is designed for a wide range of applications, from military to commercial communication systems. It is manufactured using a 0.25µm gate length pHEMT process with substrate via holes and air bridges.

It is available in chip form and in RoHS compliant SMD package 24L-QFN4x5.
