Description
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
1db
of 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.
