Description
The PD84001 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 7V in common source mode at
frequencies of up to 1GHz.
PD84001's superior gain and efficiency makes it
an ideal solution for portable radio and UHF RFID
reader.
