Frequency division switching using RF buss

A system and method for isolating a data or circuit signal, where the circuit signal has been frequency spread modulated with other such signals onto a beam signal and which beam signal has been frequency spread modulated onto an IF signal, using a buss for providing the entire IF signal to a bank of frequency agile tuning demodulators. Plural IF signals may be processed simultaneously where each tuning demodulator has access to each IF signal via a plurality of IF busses. Each tuning demodulator is capable of isolating any circuit signal from any IF signal.
