Graph: BR7-HP LQ : Semi-Adjacent Highpass
Graph 1: BR7-HP 222 / 228 LQ (> 50 dB stopband)
- Highpass removes segment of CATV spectrum below ch.23 (0 to 222 MHz), and passes upper segment above ch.25 (228 to 650 MHz)
- Transition: Fc and Fs separated by 6 MHz
- Passband loss at Fc is < 4 dB typical
- Stopband: > 55 dB typical
- Option 750 MHz or 1000 MHz passband available for some models - inquire

- Transition: Fc and Fs separated by 8 MHz
- Passband loss at Fc is < 4 dB (typical)
- Stopband: > 55 dB (typical)
- Option 1000 MHz passband available for most models - inquire
