Description
The device 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 7 V in common source mode at
frequencies of up to 1 GHz. The device 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.
Device’s superior linearity performance makes it
an ideal solution for portable radio.
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.
