Adjacent Channel Bandpass (any channel from 5 to 250 MHz)
CFAL and CFAS
Model CFAL and CFAS are designed to pass one specific TV channel, reject the adjacent channels, and all out-of -band frequencies. Channels available (CATV): T7 - T13, 2 - 13, A5 - A1, A14 - I22, 23 - 30, and TV-IF (41 to 47 MHz). Available for NTSC and ATSC system.
Operating Bandwidth: 5 to 750 MHz
Passband loss:<3.5 db (4 to 5db at band edges)
Return Loss:15 dB typical (except band edges)
CFAL- rejection: >30 dB on adjacent carrier, > 20 dB on rest of channel, > 35 dB out-of-band
CFAS (outdoor version of CFAL) - rejection: > 25 dB on adjacent carrier, and >15 dB on rest of channel, > 30 dB out-of -band
Custom passband: any frequency band (2 to 16 MHz wide) within 5 to 250 MHz (e.g CFAL-ch.14 -16)
Both models are also available in 50 ohms (BNC)
