CHT4694-99F
25-45 GHz Attenuator
GaAs Monolithic Microwave IC
Description
The CHT4694 is a variable 25-45GHz
attenuator designed for a wide range of
applications, from military to commercial
communication systems. The backside of the
chip is both RF and DC grounded. This helps
to simplify the assembly process.
The circuit is manufactured with a MESFET
process, 0.7µm gate length, via holes through
the substrate and air bridges.
It is supplied in chip form.

25-45 GHz Attenuator
CHT4694-99F
Biasing sequence
To obtain good performances in linearity, biasing voltage should be applied as following:
- Control of 1st stage attenuation with V1 from –5V to 0V, with V2 fixed at -5V
- Control of 2nd stage with V2 from -5V to 0V, with V1 fixed at 0V

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
