Graph: LH7-470/520 CATV General Purpose Diplexer
LH7-470/520 graph illustrates lowpass and highpass frequency responses.
- Combine two bands: 0 to 470 MHz and 520 to 760 MHz, or
- Divide 0 to 800 MHz RF-spectrum into low & high bands
- Passband loss: < 1dB lowpass, < 1.5 dB highpass
- Ripple: <1 dB
- Mutual isolation >40 dB
