Description
The T7023 is a monolithic SiGe power amplifier. It is especially designed for operation
in TDMA systems like Bluetooth, DECT, and many other ISM applications according to
FCC part 15.
Due to the ramp-control feature and a very low quiescent current, an external switch
transistor for V
S
is not required.
