Data Sheet
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 con-
stant-envelope 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
22 dBm). The input is easily
matched to 50 Ω.
Due to the high power output of
this device, it is recommended for
use under a specific set of
operating conditions. The thermal
sections of the Applications
Information 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.

... Thermal Considerations The DC power dissipation of the MGA-83563, which can be on the order of 0.5 watt, is approaching the thermal limits of subminiature packaging such as the SOT-363 result, particular care should be taken to adequately heatsink the MGA-83563. The primary heat path from the MMIC chip to the system heatsink ...

... Reliability Data.” This reliabil- ity data sheet covers the Avago family of PHEMT GaAs RFICs. Linear Amplifier Thermal Example If the MGA-83563 is used in a linear application, the total power dissipation is significantly higher than for the saturated mode. The dissipated power is greater due to ...

... The shunt-C, series-line topology is chosen based on its ability to cover the expected range of impedance to be matched and because it will pass DC bias into the output pin of the MGA-83563. (For the latter reason, impedance matching circuits using series capacitors are avoided.) In some cases, it may be more ...

... Smith chart. A series 2.5 nH inductor (L1) is then all that is required to complete the match to 50 Ω at Point C. While the input impedance of the MGA-83563 is somewhat isolated from the nonlinear effects of the saturated output stage, some empirical optimization of the input inductor may increase the input return loss still further ...

... The input power was fixed at +4 dBm for this test. The length of the series line between the output of the MGA-83563 and C2 is also part of the matching circuit. This line was not considered as a variable in the sensitivity analysis since photo- fabrication of micro-striplines on circuit boards is highly repeatable ...
