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 impulse and 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 was designed on the front panel; output level, A/V,
volume and video index all adjusted by 32 steps variable respectively;
7. Intermediate frequency input and output port;
8. High efficiency SMPS;
