Q4：What do you mean by ‘’Acceptable Specify Fo Range’’ showing on each Spec.?
That means we can make the same performance curve shift as the Frequency range that we set in the acceptable specify Fo Range. For example, Part Number:TT6755D-145M, Acceptable Specify Fo Range:125~145 MHz, customer need Fo=127 MHz, It’s because Fo=127M during the range 125~145Mhz so that the specification and performance curve of TT6755D can be tuned by Temwell to 127MHz as good as the original Fo. The Part No. would be transferred to TT6755D-127M .
