Features
1.High quality SAW filter process, low noise figure can avoid system CNR worse; suitable for professional CATV system; 2. Intermediate frequency modulated and adopt 3 SAW filters, low spur out of band; 3. Audio intermediate frequency process, high frequency video process. MCU technique is applied to audio and local oscillator to ensure high performance and stability; 4. Adopt modularization for output impulseand SMT technology is applied to MMIC circuit to ensure the unit in high reliability. IF input and output port for further operation; 5. LCD displays frequency, use up and down button to select channel or frequency; 6. Convenient control, frequency level adjustment wasdesigned on the front panel; output level, A/V, volume and video index all adjustedby 32 steps variable respectively; 7. Intermediate frequency input and output port; 8. High efficiency SMPS; 9. We can offer PAL or NTSC system standard upon customer's requests.
