SGA-4486

SGA4486Z SGA4486ZDC to 4500MHz, Cascadable SiGe HBT MMIC Amplifier DC to 4500MHz, CASCADABLE SiGe HBT MMIC AMPLIFIER Package: SOT-86 Product Description Features The SGA4486Z 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 VD = 3.2V, ID = 45mA (Typ.)
