NOTCH FILTER FORMULAS:

Center Frequency:

\(\begin{equation*}
F_{n} \ =\ \sqrt{F”_{-3dB} \ *\ F’_{=3dB}}
\end{equation*}\)

Low Frequency Stopband:
\( \begin{equation*} LF_{x} \ =\ \frac{\sqrt{( Stopband\ BW)^{2} \ +\ 4*( F_{0})^{2} \ -\ Stopband\ BW}}{2} \end{equation*}\)
High Frequency Stopband:

\(\begin{equation*}
HF_{x} \ =\ LF_{x} \ +\ Stopband\ BW
\end{equation*}\)

The actual stopband frequencies may vary at frequency and bandwidth extremes.

Time Delay:

To calculate a specific time delay from the simulated data, use the frequency of interest. Referring to the, KB4, delay simulation on page 1.5, and assuming a center frequency of 420 MHz the delay is calculated as follows:

Delay = 6.5/420*106
           = 15.48nSeconds at 420 MHz

NOTES:

TTE offers its passive filters in the smallest practical sizes available; PCB, SMT or connectorized (BNC or SMA) cases are typically utilized, depending on the specific filter design.
