WebCrystal Filters Input Third Order Intercept Point for Crystal Filters By Dennis Layne Introduction The heart of a dual conversion super hetero-dyne receiver is the Intermediate frequency (IF) filter or filters. This filter has to be approximately one channel wide. Crystal IF filters are typically used in order to achieve this bandwidth.

WebThe four element Cohn filter that forms the Intermediate Frequency (IF) Filter in the NorCal 40A is: X1 C9 C10 X2 C11 X3 C12 X4 C13 To understand the operation of this filter, the text first adds fictitious Land Celements. The unsigned reactances of Land C are equal so their series impedance is zero at f0. C9 C10 C11 X3 C12 X4 C13 X1 X2 WebThe aging of narrow and intermediate band crystal filters is almost solely dependent upon the aging of the crystals themselves. Thus, after proper conditioning, it is possible for the filters to age no more than a fraction of a part-per-million per year. This makes crystal filters ideally suited for phase-matched applications. floyd county high school staff
