This type Agile Modulator is a good choice to build MATV,SMATV or CATV as it is with full function and high performance.
CATV Adjacent Analog RF Modulator

Feature

* Intermediate frequency, double conversion frequency with SAW filter ensure low side-band interfere

* MCU technique is applied to audio intermediate frequency, video high frequency process and RF local oscillator, with high frequency stability and accuracy.

* Integrated circuit is applied to outputs, and each functional circuit of the whole unit which adopts SMT technology and with high stability.

* Excellent video and audio linearity for superior picture quality

* LED displays frequency, using up and down button to select channel and frequency.

Convenient control, frequency level adjustment is on front panel. 

* PAL or NTSC system standard upon customer's requests.
