Features

  • The machine adopts aluminum pressing, its surface adopts passive and spray-paint processing, which benefit to the cooling and electricity and anti-causticity.
  • Perfect flush Suppress circuit improved the performance of anti thunder and anti-flush.
  •  Excellent AGC performance, when the input optical power range is -7~+2dBm, the output level keep unchanged, CTB and CSO basically unchanged. GaAs amplifier device, power double output, high gain and low distortion.
  • Good stability, MTBF≥100000 hours.
  • Adjustable RF input and slope.
  • 6. The user could choose the frequency freely. There are many double filters for choice. The single type could be changed into single type and the low distribution into high distribution through the changing the plug-in unit of duplexer.

1.Choice for single net: 47~750MHz、47~862MHz

2.Choice for bi-directional net:

a、5~35/47~750MHz(keeping 1CH)

b、5~42/53~750MHz(not keeping 1CH)

c、5~65/87~750MHz(862MHz)

  • In order to protect the digital display tube, the display tube will only working when the node is open.
  • Reserved International standard manage port, easy for upgrade.
  • Input power range 2dBm~-7dBm. Input =-6dBm, output is 2dBm~-7dBm, C/N≥47dBm.
  • Two models : Standard and 4dB pre-equalization.
