Notes:
1. R1, L4, C3, and C4 are not required in actual application. These are added on demoboard to mitigate power supply noise in the test
2. Pin 3 must be left unconnected.
3. L1and L2 form the input matching network. C1, C2 and L3 form a matching network at the output of the LNA.
4. Bias control is achieved by either varying the SD voltage with/ without R2, or fixing the SD voltage to Vdd and adjusting R2 for desired
