Abstract
A method for reducing distortions of a radio frequency (RF) system includes configuring a plurality of mixers to convert between a plurality of phase signals and a plurality of RF signals, configuring a first mixer of the plurality of mixers to operate in a six-phase operating mode to reduce the distortions of the RF system, and configuring a second mixer of the plurality of mixers to operate in a three-phase operating mode to reduce power consumption of the RF system.

A method for reducing distortions of a radio frequency (RF) system, the method comprising:
- configuring a plurality of mixers to convert between a plurality of phase signals and a plurality of RF signals;
- configuring a first mixer of the plurality of mixers to operate in a six-phase operating mode to reduce the distortions of the RF system;
- configuring a second mixer of the plurality of mixers to operate in a three-phase operating mode to reduce power consumption of the RF system, at least one of the first mixer or the second mixer being coupled to a single-ended power amplifier (PA);
- and
- processing the plurality of phase signals and the plurality of RF signals through the configured first mixer.
A method for reducing distortions in a radio frequency (RF) system, the method comprising:
- producing six local oscillator (LO) signals by an LO generator, the six LO signals being fed into a plurality of mixers;
- configuring a first mixer of the plurality of mixers to operate in a six-phase operating mode to reduce the distortions in the RF system;
- configuring a second mixer of the plurality of mixers to operate in a three-phase operating mode to reduce power consumption of the RF system, at least one of the first mixer or the second mixer being coupled to a single-ended power amplifier (PA);
- and
- processing RF signals of the RF system through the configured first mixer.
A radio frequency (RF) system comprising:
- a local oscillator (LO) generator configured to generate a plurality of LO signals;
- a first mixer configured to receive six phase signals offset by 60 degrees from each other and six LO signals generated by the LO generator, the first mixer being configured to operate in a six-phase mode in which the six phase signals are mixed with the six LO signals to generate first RF signals;
- and
- a second mixer configured to receive the six phase signals and three LO signals generated by the LO generator, the second mixer being configured to operate in a three-phase mode in which the six phase signals are mixed with the three LO signals to generate second RF signals, at least one of the first mixer or the second mixer being coupled to a single-ended power amplifier (PA).
