Standard 7kW to 75kW UHF DTV Bandpass Filter Critical, Elliptical
Type: Filters, TV Bandpass
- Suitable for analog and digital TV or mobile media applications.
- Low VSWR
- Temperature compensated
- Dielectric is offering the CIF channel combiner with filter, tuned for mask filter requirements too.
Notes:
1. At ambient temperature 104ºF (40ºC), sea level, 0 PSIG.
2. Group delay variation over the pass band.
3. By reducing the average input at NB input, half of the power reduced can be added to the WB input.
$. For more than 5,000 feet (1,524m), please contact factory.
