HEAD AMPLIFIER.

■ APPLICATION

• This product is an amplifier which compensates and amplifies the damaged down and up stream signal by combiner and divider.

■ FEATURE

• Compensates for the loss caused by synthesizing the signal for each channel from the signal processor and the modulator.

• It has excellent amplifying characteristic of low noise and linear.

• By using the hybrid IC, It does the high power amplification.

※LHA-787F : One-way product has down character.

※LHA-730D : Bidirectional product has down and up character.

■ APPLICATION

• This product is a device that mix transmission of MATV band and SMATV IF band (950 ~ 2,150MHz).

■ FEATURE

• MA band signal processor and the signal of each channel coming from the modulator is compensated sufficiently for the loss caused by the mixer synthesis.

• The LED lamp on front panel makes it easy to control tilt & gain and grasp the over modulation status.

• There is a monitor terminal it can be monitor to the output signal

• It has a function to supply LNB operating power (DC 15V) to the amplifier input terminal and a select switch that can select it selectively.
