25-45 GHz Attenuator
CHT4694-99F
Biasing sequence
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
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
