Figure 7. Demoboard and application schematic diagram
Notes
x The module is fully matched at the input and output RF pins. The RFinput pin, pin1, is directly connected to a shunt inductor that is grounded. The
RF output lter blocks DC. Best noise performance is obtained using high-Q wirewound inductors. This circuit demonstrates that low noise gures
are obtainable with standard 0402 chip inductors.
x C2 and L2 form a matching network that aects the frequency response and linearity of the LNA, these can be tuned to optimize gain and return
loss.
x L1 and R1 isolates the demoboard from external disturbances during measurement. It is not needed in actual application. Likewise, C1 and C3
mitigate the eect of external noise pickup on the Vdd and Vsd lines respectively. These components are not required in actual operation.
x Bias control is achieved by either varying the Vsd voltage with/ without R2, or xing the Vsd voltage to Vdd and adjusting R2 for the desired current.
