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.
