Notes
• L1 and L form the input matching network. The LNA
• L3 is an output matching inductor.
• C5 is a RF bypass capacitor.
• PRL1 is a network that isolates the measurement de-
• Bias control is achieved by either varying the VSD voltage
• Higher gain and IP3 performance can be obtained by
• For low voltage operation such as 1.5V or 1.0V, the R1
module has a integrated coupling and DC-blocking ca-
pacitors 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 040 chip inductors. Replacing L1, L and L3 with
high-Q wirewound inductors (eg. Cilcraft 040CS series)
will yield 0.1dB lower NF and 0.6dB higher Gain.

the effect of external noise pickup on the VSD and VDD
lines. These components are not required in actual opera-
tion.

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