    operation of current bleeding mixer

    hi I have just started using cadence, can anyone guide me how to check whether a mixer is functioning properly, i.e. it is downconverting the frequency?
    Thanks

    Re: operation of current bleeding mixer

    The most important parameters of a mixer that need to be measured are:
    -Conversion Gain or Loss
    -Linearity (Input Intercept Point as IIP3)
    -Spurious products
    -Ports Isolation
    -Noise Figure

    thanks...but how should i know that the mixer is downconverting the frequency, because for any circuit NF and Conversion gain still exists even if doesnot function as a mixer ....

    Use PSS/PXF or PSS/PAC with local signal as only one large signal.

    See the followings.
