Description
The T0930 is a monolithic integrated power amplifier IC. The device is manufactured
with Atmel’s Silicon-Germanium (SiGe) technology and has been designed for use in
900-MHz two-way pagers, PDAs, meter readers and ISM phones.
With a single supply voltage of 2.4 V to 3.4 V and a neglectable leakage current in
power-down mode, the pager amplifier only needs few external components and thus
helps to reduce system costs. It is suited for operation in CW mode.
