Crystal filter cf3
WebCrystal filters are widely used today to provide the IF selectivity in communications receivers. As the use of two-way radio equipment increased, improved frequency utilization was a necessity. For example, the VHF band (132 – 174 MHz) was originally established for 120 kHz channel spacing for commercial 2-way FM radio use. WebAug 22, 2008 · We first look at the effects of the thickness ratio t 1 / t 2 by comparing FOM curves of CF1, CF2, and CF3 in Figure 3. We keep the thickness of the micrometer fiber layer t 1 constant, and change the thickness of the nanofiber layer from 0.15 μm to 1 μm.
