Description
The STAP57045 is a common source N-channel,
enhancement-mode lateral field-effect RF power
transistor. It is designed for high gain, broad band
commercial and industrial applications. It
operates at 28 V in common source mode at
frequencies of up to 1 GHz. STAP57045 boasts
the excellent gain, linearity and reliability of ST’s
latest LDMOS technology mounted in STAP1
plastic RF power package.
STAP package has been specially optimized for
RF needs and offers excellent performances and
ease of assembly.
