DC to 500MHz, CASCADABLE InGaP/GaAs
HBT MMIC AMPLIFIER
Package: SOT-89
Product Description
RFMD’s SBF-4089(Z) is a high performance InGaP/GaAs Heterojunction BipolarTransistor MMIC Amplifier. A Darlington configuration designed with InGaP processtechnology provides broadband performance up to 0.5GHz with excellent thermalperformance. The heterojunction increases breakdown voltage and minimizes leak-age current between junctions. Cancellation of emitter junction non-linearitiesresults in higher suppression of intermodulation products. Only a single positivesupply voltage, DC-blocking capacitors, a bias resistor, and an optional RF chokeare required for operation.

SBF-4089(Z)Evaluation Board LayoutRbiasCDLCCBL1CBMounting Instructions1. Note: For broadband RF unconditional stability do not put GND vias under the exposed backside GND paddle.2. Solder the copper pad on the backside of the device package to the ground plane.3. USe a large ground pad area with many plated through-holes as shown.4. We recommend 1 or 2 ounce copper. Measurement for this data sheet were made on a 31mil thick FR-4 board with 1 ouncecopper on both sides.PinFunction1 RFIN2, 43GND RFOUT/BIASDescriptionRF input pin.
