      LKM750-2 adjacent frequency modulators correspond to Category- Technical Index of the state respectively. Users may choose a suitable one according to their need.     Modulate video and audio signals to 38MHz and 31.5MHz respectively. In order to make the image modulation depth is more than 87.5% and the inter-modulation index, a loop-type mixer is adopted. Moreover, the A/V ratio, video and sound modulation degree are adjustable so as to the modulator is in the optimal state when different signal sources appear.     A phase-locked loop (PLL) is available for the sound 6.5MHz±1KHZ so that the sound frequency stays stable and accurate and the sound is clear and will not change as the temperature changes.     PLL is used for local oscillator of frequency converter so that the image frequency stays stable and accurate.     A saw filter is used to filter waves of intermediate frequency so that the
