1. Description
1.1
Process
This 5-GHz power amplifier (PA) is designed using Atmel’s Silicon-Germanium (SiGe)
process and provides high efficiency.
1.2
Circuitry
The PA, ATR7040, consists of a three-stage amplifier with a typical output power of
25 dBm. The output stage was implemented using an open-collector structure. Power
up, power down, and output level are controlled at bias control pin 6 (Vctl).

3. Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
