• ESD PROTECTION
• IS-97 CDMA PERFORMANCES
DESCRIPTION
The LET20030S is a common source N-Channel,
enhancement-mode lateral Field-Effect RF power
transistor. It is designed for high g ain, broad band
commercial and industrial applications. It operat es
at 26 V in common sou rce mod e at frequencies up
to 2 GHz. LET20030S 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. LET20030S’s
superior linearity performance makes it an ideal
solution for base station applications.
