T7024藍牙芯片資料介紹
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 and WDCT.
Due to the ramp-control feature and a very low quiescent current, an external switch
transistor for VS is not required.
