Product Description
Stanford Microdevices’ SXA Series are high performance
GaAs Heterojunction Bipolar Transistor (HBT) MMICs
housed in thermally-efficient plastic packages. These GaAs
HBT MMICs are fabricated using molecular beam epitaxial
growth technology for consistent and repeatable
performance from wafer to wafer and lot to lot.
These amplifiers utilize Darlington pair topology for
broadband performance from DC-2.5 GHz. Heterojunction
technology minimizes emitter non-linearities resulting in high
TOIP to P1dB spreads, ideal for high-linearity applications.
Also available in die form, these devices are fully
passivated for ruggedness and durability. Both bond pad
and backside metal are Au-metallized for compatability with
automatic and manual die attach and bonding equipment.
