PD57070-E PD57070S-E RF POWER transistor, LdmoST plastic family N-channel enhancement-mode, lateral MOSFETs Features Excellent thermal stability Common source configuration P = 70 W with 14.7dB gain 945 MHz/28 V OUT New RF plastic package Description PowerSO-10RF (formed lead) 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 up to 1 GHz. The device boasts the excellent gain, linearity and reliability of STs latest LDMOS technology mounted in the first true SMD plastic RF power package, PowerSO-10RF. PowerSO-10RF Devices superior linearity performance makes it (straight lead) 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 Figure 1. Pin connection specially optimized for RF needs and offers Source excellent RF performances and ease of assembly.
