+22 dBm P
SAT
3V Power Amplifier
for 0.5 – 6 GHz Applications
Data Sheet
Description
Avago’s MGA-83563 is an easy-to-use GaAs RFIC amplifier
that offers excellent power output and efficiency. This
part is targeted for 3V applications where constant-en-
velope modulation is used. The output of the amplifier is
matched internally to 50Ω. However, an external match
can be added for maximum efficiency and power out
(PAE = 37%, P
o
= 22 dBm). The input is easily matched
to 50 Ω.
Due to the high power output of this device, it is recom-
mended for use under a specific set of operating condi-
tions. The thermal sections of the Applications Informa-
tion explain this in detail.
The circuit uses state-of-the-art PHEMT technology with
proven reliability. On-chip bias circuitry allows operation
from single supply voltage.

3. Measured using the final test circuit of Figure 1 with an input power of +4 dBm.
4. Standard Deviation number is based on measurement of at least 500 parts from three non-consecutive wafer lots during the initial characteriza-
tion of this product, and is intended to be used as an estimate for distribution of the typical specification.
5. For linear operation, refer to thermal sections in the Applications section of this data sheet.
