DC to 4000MHz, CASCADABLE SiGe HBT
MMIC AMPLIFIER
Package: SOT-86
Product Description
Features
The SGA6586Z is a high performance SiGe HBT MMIC Amplifier. A Darling-
ton configuration featuring one-micron emitters provides high FT and
High Gain: 18.4dB at
1950MHz
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.
