■ 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
