Preliminary
Product Description
Sirenza Microdevices’ SBB-5089 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 5V supply, the
SBB-5089 does not require a dropping resistor as compared to typical
Darlington amplifiers. The SBB-5089 product is designed for high linearity
5V gain block applications that require small size and minimal external
components. It is internally matched to 50 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 2002/95. This package is also manufactured with green molding
compounds that contain no antimony trioxide nor halogenated fire retardants.

Operation of this device beyond any one of these limits may cause
permanent damage. For reliable continuous operation, the device
voltage and current must not exceed the maximum operating
values specified in the table on page one.

devices must be observed.
Mounting Instructions
1. Solder the copper pad on the backside of the device package to
the ground plane.
2. Use a large ground pad area with many plated through-holes as
shown.
3. We recommend 1 or 2 ounce copper. Measurement for this
datasheet were made on a 31 mil thick FR-4 board with 1
ounce copper on both sides.
