Preliminary
1. Description
The ATR0981 is a monolithic IC manufactured using Atmel’s advanced SiGe technology. The IC performs a transmit and receive front-end function, dedicated for a
frequency range of 300 MHz to 500 MHz. It consists of a Low-Noise Amplifier (LNA)
and a Power Amplifier (PA) with good Power-added Efficiency (PAE).
