ATR7035
Description
Summary
Process
The 5-GHz power amplifier is designed using Atmel’s Silicon-Germanium (SiGe) pro-
cess and provides excellent noise performance as well as good power-added
efficiency.
Circuitry
The PA consists of a 2-stage amplifier with a maximum output power of 28 dBm. The
output stages were realized using an open-collector structure. The IC features 50-Ω
input matching. Power-up/down and output level are controlled at bias control pin 6
(V_CTL).
