NPN microwave power transistor PTB23003X
FEATURES
• Diffused emitter ballasting resistors providing excellent
current sharing and withstanding a high VSWR
• Interdigitated structure provides high emitter efficiency
• Multicell geometry gives good balance of dissipated
power and low thermal resistance
• Localized thick oxide auto-alignment process and gold
sandwich metallization ensure an optimum temperature
profile and excellent performance and reliability.
APPLICATIONS
Common-base, class B power amplifiers up to 4.2 GHz.
DESCRIPTION
NPN silicon planar epitaxial microwave power transistor in
a metal ceramic SOT440A flange package with base
connected to the flange.
QUICK REFERENCE DATA
Microwave performance up to T
=25°C in a common-base class B circuit.
