| Summary: | To accomplish the project for in designing an active mixer and passive mixer, the
main problem is to obtain the conversion gain for the active mixer design compared to
passive mixer design. From the linearity issue, active mixer design is nonlinear compared
to passive mixer design that is more linear. Besides that, the active mixer has better
isolation compared to the passive mixer. This project will be created by applying the
circuit design into simulation from HP-ADS (Advanced design system) to the circuit board
that is appropriate and and analyzation will be made for both designs. The results at the
conversion gain, linearity issue, and port-to-port isolation will be compared for both of the
design and will be discussed according to the theory. Additionally, all problem that may
occur from the design and analyzation will be considered and the inaccurate result from
measurement will be discussed. The mixer will be designed in down conversion system.
This circuit is designed by using the hardwares and the surface mount chip elements that
are in effective cost and applicable with the practical usage. Therefore, the design of
mixer and the analyzation can be make without any intricacy. Hopefully the design of the
active mixer and passive mixer using FET transistor can be continued and improved for
the usage in variety of application in the future.
