Description
Process
The 5-GHz power amplifier is designed in Atmel’s advanced Silicon-Germanium
(SiGe) process and provides excellent noise performance as well as good power-
added efficiency.
Circuitry
The PA consists of a two-stage amplifier with a linear output power of 21 dBm. The
output stage was realized using an open-collector structure. Power-up/down and out-
put level are controlled at bias control pin 6 (Vctl). An on-chip power detector provides
a voltage proportional to the output power.
