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

Due to the ramp-control feature and a very low quiescent current, an external switch
