Abstract:
1. A dual radio frequency (RF) receiver circuit comprising: local oscillator circuitry adapted to provide a first local oscillator (LO) signal having a first LO frequency and a second LO signal having a second LO frequency; a first RF mixer coupled to the local oscillator circuitry and adapted to: a second RF mixer coupled to the local oscillator circuitry and adapted to: the RF receiver circuit adapted to process substantially simultaneously two different data streams that arrive as the first RF input signal and the second RF input signal respectively; and further comprising control circuitry coupled to the local oscillator circuitry and adapted to select one of a first operating mode, a second operating mode, a third operating mode, and a fourth operating mode, such that: during the first operating mode, the first RF mixer is further adapted to: during the second operating mode, the first RF mixer is further adapted to: during the third operating mode, the first RF mixer is further adapted to: during the fourth operating mode, the first RF mixer is further adapted to: during the first operating mode, the second RF mixer is further adapted to: during the second operating mode, the second RF mixer is further adapted to: during the third operating mode, the second RF mixer is further adapted to: during the fourth operating mode, the second RF mixer is further adapted to:
