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.
Apart from telephone applications, the T0905 can also be used for car identification
systems and several other wireless communication systems. The single supply volt-
age operation at +3.5 V and a negligible leakage current in power-down mode enable
a remarkable simplification of the application’s power management.
