Complexities in RF Circuits
* Accumulation of uncertainty / error - Simulation vs Actual:
Model -> Simulation Program -> Variation in Parts
--- for several different simulation programs used to model different
aspects or parts of circuits
* Uncertainty in Meeting Specifications
Scheduling invention / Changing Specs
* Frequency and Time Domain
* Lumped elements ->
* Metal lines -> Transmission line ‚Passive Circuits, antennae
* Every component includes
parasitic resistance, capacitance, and/or inductance
* Output and input impedances interact
* Impedance matching strongly effects performance in system
* Impedance matching is complicated because
* Stray signals are readily capacitively or inductively coupled into signal path
