SGA6489Z SGA6489ZLow Noise, High Gain SiGe HBT DC to 3500MHz, CASCADABLE SiGe HBT MMIC AMPLIFIER Package: SOT-89 Product Description Features The SGA6489Z 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. Gain & Return Loss vs. Frequency GaAs HBT VD= 5.1 V, ID= 75 mA (Typ.)
