T0905-TSPH
T0905-TSPH Datasheet
The T0905 is a monolithic integrated power amplifier IC manufactured with Atmel’s Silicon-Germanium SiGe process. Due to its open architecture, the device can be used either as a two or three-stage amplifier. Every stage can be matched individually, thus allowing applications in a wide frequency range. The T0905 can be used from 135 MHz up to 600 MHz in both linear and non-linear saturated mode. The power gain can be set dynamically by means of an analog control input optionally for each single stage or for the entire power amplifier. Constant gain mode is also possible. The T0905 is suited for CW mode up to 35 dBm. These features, including wide power ramp control, make the T0905 a very flexible power amplifier for many different applications.

Apart from telephone applications, the T0905 can also be used for car identification systems and several other wireless communication systems. The single supply voltage operation at V and a negligible leakage current in power-down mode enable a remarkable simplification of the application’s power management.
