Description
The PD55008L-E 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 12V in common source mode at
frequencies up to 1GHz.
PD55008L-E boasts the excellent gain, linearity
and reliability of STH1LV latest LDMOS
technology mounted in the innovative leadless
SMD plastic package, PowerFLAT™. PD55008L-
E’s superior linearity performance makes it an
ideal solution for car mobile radio.
