Custom Notch Trap Specification (see fig.1)

For prompt assistance on trap requirements, please provide the following info:

1. Notch Frequency: Specify Fo and/or stopband width (in MHz)
2. Attenuation ( in dB): Specify 5dB to 70dB¹
3. Specify FL & Fu: critical frequencies (adjacent to Fo) to pass with minimal loss
4. Selectivity: 3dB BW - depends on Fo -inquire
5. Allowable Passband: Fb & Fs (in MHz)
6. Passband loss & ripple: 1dB ± .5 dB typ.
7. Connectors: Type F (female) std²
8. Impedance: 75 ohms²
9. Model #: CR7-HQ (see examples above)
10. Operation: Indoor, outdoor - inquire
11. Allowable Dimensions: inquire
12. Specific Requirements: Advise us

Notes:

1. Attenuation: Notches can be fine tuned for a specific attenuation level, they can also be combined for greater attenuation, notch width, and frequency stability.
2. Connector options - 75 ohms: Type F (male), and BNC (female); 50 ohms: Type N, BNC, SMA. (female); and 300 ohms : screw terminals.
