Product Description Sirenza Microdevices SBB89 is a high performance InGaP HBT MMIC amplifier utilizing a Darlington configuration with an active bias network. The active bias network provides stable current over temperature and process Beta variations. Designed to run directly from a V supply, the SBB89 does not require a dropping resistor as compared to typical Darlington amplifiers. The SBB89 product is designed for high linearity V gain block applications that require small size and minimal external components. It is internally matched to ohms. The matte tin finish on Sirenza s lead-free package utilizes a post annealing process to mitigate tin whisker formation and is RoHS compliant per EU Directive /9. This package is also manufactured with green molding compounds that contain no antimony trioxide nor halogenated fire retardants. 3 1-3 Gain & Return Loss vs. Frequency (w/ App. Ckt.)

For reliable continuous operation, the device voltage and current must not exceed the maximum operating values specified in the table on page one. Bias Conditions should also satisfy the following expression: I D V D < (T J - T L ) / R TH, j-l T L =T LEAD ESD Class 1C Appropriate precautions in handling, packaging and testing devices must be observed. Mounting Instructions 1. Solder the copper pad on the backside of the device package to the ground plane.. Use a large ground pad area with many plated through-holes as shown. 3. We recommend 1 or ounce copper. Measurement for this datasheet were made on a 31 mil thick FR- board with 1 ounce copper on both sides.
