Description
The T7024 is a monolithic SiGe transmit/receive front-end IC with power amplifier,
low-noise amplifier and T/R switch driver. 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.
