900 MHz LNA Design
To demonstrate the versatility of the MGA-53543, the
following example describes a cellular band Low Noise
Amplifier (LNA) design. The methodology for a 900 MHz
LNA design differs from the previous examples in that
only the input match affects noise figure. Thus, optimiz-
ing for minimum noise figure entails matching only the
input to Γ
matched to S for better gain or Γ
Figure 7 shows the complete schematic for a 900 MHz
low noise amplifier design and Table 5 describes the re-
quired components.

Performance of MGA-53543 at 900 MHz
Biased with a +5 Volt supply MGA-53543 delivers a Noise
Figure of 1.33 dB at 900 MHz. This number is higher than
NF
ponents with parasitic losses. A microstip or distributed
element match may improve noise figure by . dB. Gain is
measured to be 17.4 dB as shown in Figure 8. Input and
output VSWR are both better than :1, with input return
loss of 5 dB and output return loss at 17.5 dB shown in
Figure 9.
