DESCRIPTION

The LET9060S 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 26 V in common source mode at frequencies up
to 1 GHz. LET9060S boasts the excellent gain,

linearity and reliability of ST’s latest LDMOS
technology mounted in the first true SMD pla stic
RF power package, PowerSO-10RF. LET9060S’s
superior linearity performance makes it an ideal
solution for base station applications.
