Description

Preliminary

Process

The 5-GHz power amplifier is designed in Atmel’s advanced Silicon-Germanium

(SiGe) process and provides excellent linearity and noise performance as well as

good power-added efficiency.

Circuitry

The PA consists of a two-stage amplifier with a P_1dbof 26 dBm. The output stage was

realized using an open-collector structure. Power-up/down and output level are con-

trolled at bias control pin 6 (VCTL). An on-chip power detector provides a voltage

proportional to the output power.
