DESCRIPTION
The PD55008 is acommon 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 12V in common source mode at frequencies of
up to 1GHz. PD55008 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. PD55008’s superior linearity performance makes it an ideal solution for car mobile 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.
