2.2 About Bandwidth Extension
Equipped with option R&S SMW-K555, the R&S SMW allows you to extend band-
widths of I/Q modulated signals. A practical approach is to superimpose RF signals
with center frequencies close to each other. The bandwidths of the modulated base-
band signal overlap. The figure
Figure 2-1 illustrates the superposition of two adjacent
baseband signals band A (bandwidth f
BW A
, center frequency f
c A
) and band B (band-
width f
BW B
, center frequency f
c B
).
