ATR0906

www.DataSheet4U.com Features 35 dBm Output Power in CW Mode High Power Added Efficiency (PAE) Single Supply Operation (No Negative Rail) Simple Analog Power Ramp Control Low Current Consumption in Power-down Mode (Typically ≤15 mA) Small SMD Package (PSSOP28 with Heat Slug) Applications Professional Phones Hands-free Sets ISM Band Application Wireless Infrastructure Pre-amplifiers 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 flexible 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 simplify the power management of the application. Figure 1.
