DESCRIPTION
The LET9045S 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 up
to 1 GHz. LET9045S boasts the excellent gain,
linearity and reliability of ST’s latest LDMOS
technology mounted in the first true SMD plastic
RF power package, PowerSO-10RF. LET9045S’s
superior linearity performance makes it an ideal
solution for base station applications.
