Notes
x L3 and the module’s internal input pre-match form the input matching network. The RFin pin, pin 3, is directly connected to a shunt inductor that
x C2 and L2 form a matching network at the output of the LNA, which can be tuned to optimize gain, output return loss and linearity. For example,
x L1 and R1 isolates the demoboard from external disturbances during measurement. It is not needed in actual application. Likewise, C1 and C3
x The output of the module is internally ac-coupled to pin 8.
x Bias control is achieved by either varying the SD voltage with/ without R2, or fixing the SD voltage to Vdd and adjusting R2 for the desired current.

is grounded. The RF output filter blocks DC. 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 L2 and L3 with high-Q wirewound inductors (eg. Coilcraft 0402CS
series) will yield lower NF and higher Gain.
higher gain can be obtained by increasing the value of C2 but at the expense of stability.
mitigate the effect of external noise pickup on the Vdd and SD lines respectively. These components are not required in actual operation.
R2 = 3.9 kOhm will result in 6mA when Vdd=Vsd = 2.7V and 4mA when Vdd = Vsd = 1.8V.
