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).
