Rf Circuit. The output of the rf stage is one input of a mixer. A local oscillator lo is the other input.
Time varying voltages and currents generate electromagnetic energy that propagates in the form of waves. For the receiver the signal from the antenna is amplified in the radio frequency rf stage. Typically such circuits must operate at radio frequency and power levels which imposes special constraints on their design.
The basic concept of operation is as follows.
