Patent ID: 7782827

Claim:
An apparatus for processing N number of input signals having a common frequency, said apparatus comprising: at least N−1 number of serrodyne modulators for modulating N−1 of said N number of input signals into N−1 number of modulated signals; a combiner for combining said modulated signals along with one non-modulated signal into an aggregate signal; at least N−1 number of circulators for receiving at least part of said aggregate signal; N−1 number of demodulators for demodulating said aggregate signal, each said demodulator corresponding to one of said modulators; and N number of duplexer filters each corresponding to one of said N number of input signals; wherein said circulators, said demodulators, and said duplexer filters, are arranged in series so as to pass each of N number of demodulated portions of said aggregate signal to a single Radio Frequency (RF) output and each of said demodulated portions being substantially identical to one of said N number of input signals.
