DESCRIPTION
The LET21008 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 2.1 GHz. LET21008 boasts the excellent gain,
linearity and reliability of ST's latest LDMOS
technology mounted in the innovative leadless
SMD plastic package, PowerFLATTM.
LET21008's superior linearity performance makes
it an ideal solution for base station applica-
tions.
