Description
The T0980 is a monolithic IC manufactured with Atmel's advanced SiGe technology.
The IC performs a transmit and receive front-end dedicated for a frequency range of
400 MHz to 500 MHz. It consists of a Low-Noise Amplifier (LNA) and a Power Ampli-
fier (PA) with good Power Efficiency (PAE).
Electrostatic sensitive device.
Observe precautions for handling.
