SDA-2000 Datasheet, PDF (7/8 Pages) RF Micro Devices – GaAs Distributed Amplifier

SDA-2000
Bias Sequence (Turn Device On):
VTI - Apply negative -2.0 volts. (This shuts the device off.)
VG2 - Apply positive 3.5 volts.
VDD - Apply positive 8.0 volts to the RF output bias tee.
Important - Adjust VTI between -2 to +1.0 volts to achieve IDD = 410mA nominal.
Bias Sequence (Turn Device Off):
VTI - Return to negative -2.0 volts.
VDD - Remove positive 8.0 volts to the RF output bias tee.
VG2 - Remove positive 3.5 volts.
