Abstract:
1. an apparatus, comprising: circuitry configured to: receive a plurality of radio frequency signals by way of an equal plurality of inputs of the circuitry; passively split the plurality of radio frequency signals into a greater plurality of radio frequency signals; passively attenuate a first radio frequency signal of the greater plurality of radio frequency signals; passively delay the first radio frequency signal of the greater plurality of radio frequency signals by a predetermined delay, wherein passively delaying the first radio frequency signal comprises utilizing a cable selected from a plurality of cables, wherein each cable of the plurality of cables is associated with a fixed delay, wherein the fixed delay is determined by the length of the cable; passively phase shift the first radio frequency signal of the greater plurality of radio frequency signals; and couple the first radio frequency signal of the greater plurality of radio frequency signals to one or more outputs of the circuitry, wherein the plurality of radio frequency signals are emulated, input to output, exclusively at the respective radio frequency without:
