Applications Information
A flexible applications board topology has been developed to demonstrate the performance of the
MBC13900 at 900 and 1900 MHz. The designs are a compromise of the competing performance
requirements of gain, noise figure, input third-order intercept point (IIP3) and return losses. PCB, samples
and assembly information is available from Freescale under part number KITMBC13900.

900 MHz LNA
Figure 18 shows the schematic and Figure 19 shows the component placement for a 900 MHz LNA. The
design goals for the circuit are:
NF < 1.2 dB
Gain > 19 dB
Return Loss > 10 dB, input and output
Unconditional stability from 100 MHz to 6 GHz.
