= 3 W with 17dB gain @ 500 MHz / 12.5 V
Description
The PD55003-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 PD55003 boasts
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 PD55003’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
