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 V
S
is not required.

Electrostatic sensitive device.
Observe precautions for handling.
5. Handling
Do not operate this part near strong electrostatic fields. This IC meets class 1 ESD test require-
ment (HBM in accordance to EIA/JESD22-A114-A (October 97) and class A ESD test
requirement (MM) in accordance to EIA/JESD22-A115A.
3. Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
