Wireless communication device with a low noise receiver

A wireless communication device comprising:

• a radio frequency antenna;
• and
• a transceiver including a baseband subsystem and a receiver, the receiver between the antenna and the baseband subsystem, the receiver including a downconverter configured to generate a plurality of output phases within a local oscillator period based on (i) a radio frequency signal and (ii) a respective plurality of local oscillator signals, the plurality of output phases organized into at least K groups where K is an integer of four or greater, each nth group of the K groups including nth and (n+K)th output phases of the plurality of output phases, n being an integer between 0 and K−1, and the receiver further including a differencing stage configured to difference the nth and (n+K)th output phases of each respective group of the K groups, resulting in gain-added output phases.

A radio frequency module comprising:

• a downconverter configured to generate a plurality of output phases within a local oscillator period based on a radio frequency signal, the plurality of output phases organized into at least K groups where K is an integer of four or greater, where each nth group of the K groups includes nth and (n+K)th output phases of the plurality of output phases, and where n is an integer between 0 and K−1;
• and
• a differencing stage configured to difference the nth and (n+K)th output phases of each respective group of the K groups, resulting in gain-added output phases.

A wireless communication device comprising:

• an antenna configured to wirelessly transmit and receive radio frequency signals;
• and
• a receiver in communication with the antenna, the receiver including a downconverter configured to generate a plurality of output phases within a local oscillator period based on a radio frequency signal received by the antenna, the plurality of output phases organized into at least K groups where K is an integer of four or greater, each nth group of the K groups includes nth and (n+K)th output phases of the plurality of output phases, where n is an integer between 0 and K−1, and the receiver being further configured to difference the nth and (n+K)th output phases of each respective group of the K groups, resulting in gain-added output phases.
