• L1 and L2 form the input matching network.
• L3 is an output matching inductor.
• C5 is a RF bypass capacitor.

The LNA module has a integrated coupling
and DC-blocking capacitors at the input and
output. Best noise performance is obtained
using high-Q wirewound inductors. This
circuit demonstrates that low noise figures
are obtainable with standard 0402 chip
inductors. Replacing L1, L2 and L3 with high-
Q wirewound inductors (eg. Cilcraft 0402CS
series) will yield 0.1dB lower NF and 0.6dB
higher Gain.

disturbances. C3 and C4 mitigates the effect
of external noise pickup on the VSD and VDD
lines. These components are not required in
actual operation.

obtained by increasing the supply current.
This can be achieved by reducing the value
for R1 to obtain desired current.
