900 MHz HLA Design
Optimizing the MGA-53543 for maximum linearity at the
Cellular band follows very similar to that of 1900 MHz,
except that the input and output tuning conditions will
change according to the linearity table on the data sheet.
Figure 14 below shows the schematic diagram for a com-
plete 900 MHz circuit using Γ
0.05 ∠-165°. Table 4 shows the component parts list
used.
An optional .Ω resistor at the input helps resistively load
the amplifier and improve stability but slightly degrade
noise figure.

Performance of MGA-53543 at 900 MHz
At 900 MHz MGA-53543 delivers OIP3 of 40 dBm along
with a noise figure of 1.43 dB. Gain is measured to be
17.1 dB and input return loss is 13.7 dB and output re-
turn loss is 13.3 dB as shown in Figures 16 and 17. P1dB
is 18.8 dBm.
