Full Spectrum Receiver for Cable ReceptionCurrent cable receivers use 1 tuner per channel, or 1 tuner for N channels (N= 4 to 8 channels) bonded in a limited bandwidth
(100MHz-BW receivers) & 1 Tuner consumes ~1W
Cable Operators ask for multi-channel reception (1632 channels) over the complete cable RF band (50MHz1GHz)
at a low power consumption FULL SPECTRUM RECEIVER
