Wideband IF Double-Conversion Receiver
The wideband IF double-conversion (WIFDC) receiver shown in Figure 8.5 employs
a two-step down-conversion scheme similar to that of the conventional super-
heterodyne receiver. The essential difference between the WIFDC and the super-
heterodyne receivers is that in a WIFDC receiver, the second LO frequency (rather
than the fi rst LO frequency as in the super-heterodyne case) is programmable and
can be used to select the desired signal channels. In comparison with the zero-IF
receiver, the WIFDC receiver mitigates the errors due to the LO self-mixing by
choosing non-zer ...
