below for such adjustment similarly control signals may be provided to lo amp control 690 to set the lo frequency and programmable demodulator 675 to suphet or dcr mode also depicted in fig6 is a demarcation line 6000 a 6000 b which denotes to upper left a first portion of rf front end 600 which is depicted in fig7 according to an embodiment of the invention with one potential circuit configuration targeted to operation over 0 0001 ghz 25 ghz to the lower right of demarcation line 6000 a 6000 b a second portion of rf front end 600 is depicted in fig8 according to an embodiment of the invention with one potential circuit configuration targeted to operation over 0 0001 ghz 25 ghz it would be evident to one skilled in the art that other circuit implementations may be provided for the same operating frequency range with different sub divisions of the band into multiple frequency bands and their processing discretely or in combination it would be evident to one skilled in the art and as depicted below in respect of fig7 for example that the order of functional blocks may in some embodiments of the invention be varied for all frequencies or for one or more predetermined frequency ranges only referring to fig7 there is depicted rf front end section 700 according to an embodiment of the invention with one potential circuit configuration targeted to operation over 0 0001 ghz 25 ghz and representing the upper left portion of the rf front end 600 in fig6 as denoted by the demarcation line 6000 a 6000 b accordingly rf signals to be processed analysed are received at antenna input 700 a these signals are coupled to first rf router 755 a.
