Why do we use cascoding amplifier?
Do the matching of LNA on the Smith Chart.
How to generate I/Q signals on chip.
RF switches, MOS transistors, LNA topology.
Describe the biasing scheme you used for an LNA project, and why you chose that biasing scheme.
what is NF
Smith charts for LNA matching + LNA design (gain/NF/IIP3 optimization) + Inductor design + RF Switch design + OpAmps/LDOs + Bandgaps
Since I work for a big RFIC giant in San Diego and Microchip had to compete with it therefore their questions seemed not focused on testing me rather were focused on my experience. They tried hard to learn and get a word out of me regarding my current experience but I kept it professional . After they failed they declined me an offer saying that they could not get high compensation aligning with my experience.
Questions include VCO, bias, bandgap reference, transceiver cascaded NF, IP3 equations.
