5.8 GHz WDCT
Power Amplifier
ATR7040
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).
