Description
The PD55015-E 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 12 V in common source mode at
frequencies of up to 1 GHz. The PD55015-E
boasts the excellent gain, linearity and reliability
thanks to ST’s latest LDMOS technology mounted
in the first true SMD plastic RF power package,
the PowerSO-10RF.
The PD55015-E’s superior linearity performance
makes it an ideal solution for car mobile radios.
The PowerSO-10RF plastic package is designed
for high reliability, and is the first JEDEC-
approved, high power SMD package from ST. It
has been optimized for RF requirements and
offers excellent RF performance and ease of
assembly.
Mounting recommendations are provided in
application note AN1294, available on
