描述 Description

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.
