Description
The PD84002 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 7 V in common source mode at
frequencies of up to 1 GHz.
PD84002’s superior gain and efficiency makes it
an ideal solution for portable radio and UHF RFID
reader.
