Description
The ATR0906 is a monolithic integrated power amplifier IC manufactured with Atmel's
Silicon-Germanium (SiGe) process. Due to its open architecture it can be used either
as a two or three-stage amplifier. Every stage can be matched individually which
allows applications in a wide frequency range. The ATR0906 can be used from
600 MHz up to 1 GHz in both linear and non-linear (saturated) mode. The analog
control input sets dynamically the power gain (either for every single stage or the
entire power amplifier).Constant gain mode is also possible. The ATR0906 is suited for
the CW mode up to 35 dBm.
All these features, including wide power ramp control, makes the ATR0906 a very flex-
ible power amplifier serving many different applications.
In addition to phones, the application range includes car identification systems and
various wireless communication systems. The single supply voltage operation at
+3.5 V and a negligible leakage current in power-down mode allow to significantly sim-
plify the power management of the application.
