SGA7489Z SGA7489ZDC to 3000MHz Silicon Germanium HBT Cascadable Gain Block DC to 3000MHz SILICON GERMANIUM HBT CASCADABLE GAIN BLOCK Package: SOT-89 Product Description Features The SGA7489Z is a high performance SiGe HBT MMIC Amplifier. A Darlington 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 intermodulation products. Only two DC-blocking capacitors, a bias resistor, and an optional RF choke are required for operation.
