35W 13.6V 870MHz LDMOS in PowerSO-10RF plastic package
  • active Active

The PD85035-E is a common source N-channel, enhancement-mode lateral field-effect RF power transistor. It is designed for high gain, broadband commercial and industrial applications. It operates at 13.6 V in common source mode at frequencies of up to 1 GHz. PD85035-E 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. PD85035-E’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. Mounting recommendations are available in (look for application note AN1294).
