Product Description
The SGA4286Z is a high performance SiGe HBT MMIC Amplifier. A Darling-
ton configuration featuring one-micron emitters provides high FT and
excellent thermal performance. The heterojunction increases breakdown
voltage and minimizes leakage current between junctions. Cancellation of
emitter junction non-linearities results in higher suppression of intermodu-
lation products. Only two DC-blocking capacitors, a bias resistor, and an
optional RF choke are required for operation.

Operation of this device beyond any one of these limits may cause permanent dam-
age. For reliable continuous operation, the device voltage and current must not
exceed the maximum operating values specified in the table on page one.
Bias Conditions should also satisfy the following expression:
IDVD<(TJ-TL)/RTH, j-l
Caution! ESD sensitive device.
Exceeding any one or a combination of the Absolute Maximum Rating conditions may
cause permanent damage to the device. Extended application of Absolute Maximum
Rating conditions to the device may reduce device reliability. Specified typical perfor-
mance or functional operation of the device under Absolute Maximum Rating condi-
tions is not implied.
RoHS status based on EUDirective2002/95/EC (at time of this document revision).
