Description
The LET9045 is a common source N-Channel,
enhancement-mode lateral Field-Effect RF power
transistor. It is designed for high gain, broadband
commercial and industrial applicatios. It operates
at 28 V in common source mode at frequencies of
up to 1 GHz. LET9045 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. LET9045’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).
