Abstract
A configurable passive mixer is described herein. According to one exemplary embodiment, a passive mixer for a wireless receiver comprises a plurality of passive mixer cores coupled in parallel with each mixer core configured to receive a same set of radio frequency input signals and a separately driven set of local oscillator input signals. Further, each mixer core is configured to be separately enabled or disabled so that the passive mixer can be selectively configured during operation to convert the same set of radio frequency input signals to a set of downconverted output signals that satisfy a certain performance requirement or performance parameter of the passive mixer.

A passive mixer for a wireless receiver, comprising:
- a plurality of passive mixer cores coupled in parallel with each mixer core configured to receive a same set of radio frequency input signals and a separately driven set of local oscillator input signals, each mixer core configured to be separately enabled or disabled so that the passive mixer can be selectively configured during operation to convert the same set of radio frequency input signals to a set of downconverted output signals that satisfy a certain performance requirement or performance parameter of the passive mixer.
A method by a controller for controlling a passive mixer for a wireless receiver, the passive mixer having a plurality of passive mixer cores coupled in parallel, with each mixer core configured to receive a same set of radio frequency input signals and a separately driven set of local oscillator input signals, the method comprising:
- selectively configuring the passive mixer to convert the same set of radio frequency input signals to a set of downconverted output signals that satisfy a certain performance requirement or performance parameter of the passive mixer by selectively enabling one or more mixer cores and disabling any remaining mixer cores.
