发明名称 RX dual-band mixer
摘要 A dual-band input transceiver block is formed to operably receive one of a 2.4 GHz radio frequency signal or a 5.0 GHz radio frequency transceiver signal in a manner that minimizes duplication of circuitry and creates a combined circuit path for RF front end input stages for much of the input stage. The embodiments include separate amplification and mixing stages whose outputs are combined by a stabilized load with circuitry for removing a common mode feedback signal. A first input section is operably coupled to receive a first local oscillation input and a first frequency band signal input. A second input section is coupled to receive a second local oscillation input and a second frequency band signal input. Outputs of the first and second input sections are produced to a stabilized load with a common mode feedback block for removing a common mode feedback signal.
