Description Source
The PD85004 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 13.6 V in common source mode at
frequencies of up to 1 GHz.
PD85004's superior gain and efficiency makes it
an ideal solution for mobile radio. Source
