產(chǎn)品簡介：
CATV濾波器的工作帶寬為5 MHz至1220 MHz，帶通和帶阻濾波器的工作頻率為6 MHz至8 MHz，可達(dá)1220 MHz。此外，定制的CATV帶通和阻濾波器的帶寬為192 MHz，工作頻率為1800 MHz。
CATV濾波器和陷波器為NTSC信道/頻率標(biāo)準(zhǔn)，75歐姆阻抗，帶F型母連接器。它們可以根據(jù)不同的帶寬、阻抗和連接器進(jìn)行修改。
這些濾波器具有高選擇性、高衰減和低通帶紋波。
可進(jìn)行自定義。請咨詢。示例配置：PAL（8 MHz）/BNC/50歐姆。
提供了許多濾波器和陷波器的生產(chǎn)曲線圖，以說明典型的頻率響應(yīng)

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 Bandb: 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)
