■ APPLICATION
• This product is video and audio modulator to modulate video and audio signal of input bas band
into IF frequency, then convert, amplify and output as TV RF frequency.
■ FEATURE
• The high efficiency saw filter was adapted on IF part and it is suitable for adjoined channel transmit by minimizing the interference of other channel.
• The LED lamp on front panel makes it easy to grasp the over modulation status.
• There is an AURAL LEVEL ADJUST to transmit adjacent channels.
• PLL Synthesizer Circuit
