Abstract
Wireless circuitry can include a radio-frequency amplifier, a mixer configured to receive a local oscillator (LO) signal, and a power detector having an input port coupled to the radio-frequency amplifier and having a separate common mode cancellation input port configured to receive a common mode leakage signal associated with the LO signal. The wireless circuitry can further include a transformer coupled between the radio-frequency amplifier and the mixer. The input port of the power detector may be coupled to a first coil of the transformer. The common mode cancellation input port of the power detector may be coupled to the first coil or to a second coil of the transformer. One or more capacitors can be coupled between the transformer and the common mode cancellation input port of the power detector. Cancelling common mode leakage signals in this way can improve the dynamic range of the power detector.
