RF POWER transistor, LDMOST plastic family N-Channel enhancement-mode, lateral MOSFETs General features ■ Excellent thermal stability ■ Common source configuration ■ POUT = 8W with 11.5dB gain @ 500MHz / 7.5 ■ New RF plastic package

Description

The PD54008 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. PD54008 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. PD54008’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.
