Self Bias Network
Functional Application
Benefits
•
Wireless communication modules
•
MIC broadband high gain RF/Microwave modules
•
Bias line voltage divider and integrated decoupling capacitor
Physical Characteristics
•
Improves gain flatness and stability in GaAs FET
•
Simplifies assembly with 1 component
•
Miniature size: .020 x .034 (.5mm x .86mm)
Equivalent Schem atic Representation
Typical application requires 2 networks
Recom m ended M ounting:The
self Bias N etwork should be
mounted with fully metalized side down directly on the RF
ground plane for best performance.
