DC-16GHz Attenuator
CHT4660-QAG
Packaged part biasing options
To obtain good performances in linearity, biasing voltage should be applied as following:
- Control of 1^st stage attenuation with V1 from –5V to 0V, with V2 fixed at -5V
- Control of 2^nd stage with V2 from –5V to 0V, with V1 fixed at 0V

Attenuation
The RF ports are not DC blocked. There are no DC capacitors in the package.
Note
This part could be also driven in Single Voltage Control, applying the same voltage from -5V
to 0V on V1 and V2, leading to lower linearity performances.
