Lowpass Filters - CATV / MATV

Model LP7: General Purpose Lowpass

LP7 passes the lower segment of the TV/RF spectrum from 0 MHz to a specified cut-off (Fc), and reject the upper segment stopband (Fs) by >40dB. Table below lists standard LP7 models, transition frequencies, and general specifications.

For deletion filter applications, see our Lowpass Channel Eliminators.

• Economical filter offers user specified cutoff (Fc)
• Fc is available from 4.2 MHz to 800 MHz
• Passband loss: <1dB (except < 3dB at Fc)
• Passband ripple: ±. 5dB; Return loss: >15 dB typical
• In general, passband to stopband frequency transition: 5% (i.e., Fs = Fc x 1.05)
• Stopband: > 40 dB
• Operating Bandwidth 750 / 1000 MHz
• Available Indoor or outdoor enclosure
• Customizing available: more Info here

* Passband to 1000 MHz, some models - inquire
