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 28 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 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.
Mounting recommendations are available in
www.st.com/rf/ (look for application note AN1294).
