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.
The PowerSO-10 plastic package, designed to
offer high reliability, is the
approved, high power SMD package. It has been
specially optimized for RF needs and offers
excellent RF performances and ease of assembly.
