Front-End IC
1. 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® and WDCT.
Due to the ramp-control feature and a very low quiescent current, an external switch
transistor for VS is not required.
