LO harmonic filter’s 16 user programmable bands enable the user to optimally attenuate 2nd and/or 3rd LO

harmonics in order to maximize sideband rejection performance.

Selection

Uncalibrated sideband rejection can be further improved by empirically selecting the filter bank that

provides the highest rejection for a given frequency . See Table 15, Table 16 and Figure 46
