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
performance and ease of assembly. Mounting
recommendations are available in www.st.com/rf/
(look for application note AN1294).
