Description
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
