AT006N3-93
Description
The AT006N3-93 GHz GaAs FET IC non-reflective
bridged “T” attenuator provides up to 30 dB of “non-
reflective” attenuation. The control voltage requirements
are 0 to -5 V.
This attenuator has two independent voltage controls,
which must be adjusted in a prescribed manner to obtain
the desired attenuation under non-reflective conditions.
Refer to the Application Notes section, “Dual Voltage
Controlled VVA.”
Applications for these fast attenuators are AGC circuits
and variable level control in various military and
telecommunications systems.
