产品简介：

   CATV滤波器的工作带宽为5 MHz至1220 MHz，带通和带阻滤波器的工作频率为6 MHz至8 MHz，可达1220 MHz。此外，定制的CATV带通和阻滤波器的带宽为192 MHz，工作频率为1800 MHz。

   CATV滤波器和陷波器为NTSC信道/频率标准，75欧姆阻抗，带F型母连接器。它们可以根据不同的带宽、阻抗和连接器进行修改。

这些滤波器具有高选择性、高衰减和低通带纹波。

可进行自定义。请咨询。示例配置：PAL（8 MHz）/BNC/50欧姆。

  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)
