DC to 5MHz, Cascadable SiGe HBT MMIC Amplifier SGA-86(Z) DC to 5MHz, CASCADABLE SiGe HBT MMIC AMPLIFIER RFMD Green, RoHS Compliant, Pb-Free (Z Part Number) Package: SOT-86 Product Description The SGA-86 is a high performance SiGe HBT MMIC Amplifier. A Darlington configuration featuring one-micron emitters provides high F T 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 intermodulation products. Only two DC-blocking capacitors, a bias resistor, and an optional RF choke are required for operation.

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: I D V D <(T J - )/R TH, 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.
