Description
The PD57070 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 of up to 1 GHz. PD57070 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. PD57070'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 first ST JEDEC
approved, high power SMD package. It has been
specially optimized for RF needs and offers
excellent RF performances and ease of
assembly.
