Product Description
Indoor Type RF Amplifier

Description
TDA8030R is the terminal product of coaxial distribution network in CATV HFC bi-directional network. It amplifiers the RF signal, compensate the transmission loss of RF signal, and provide enough RF level for the coaxial distribution network. TDA8030R has one RF input port and one RF output port. There are totally four -20dB test ports for the input and output ports of forward and reversed path, it is convenient for debugging.
 
Feature
1. Aluminium alloy housing with perfect heat dissipation, bi-directional indoor design, convenient for use
2. Two modules for forward path, Phillips BGY885A or BGY887 in first stage, Phillips, PDI or Motorola GaAs double amplifier module; One module for reversed path with stable performance
3. Insert design for bi-directional filter, EQ, ATT, forward amplifier module and reverse amplifier module, compatible with other product, flexible and convenient for use
4.  Four -20dB test ports for the input and output ports of forward and reversed path,  convenient for monitoring the level of reverse path

5. 862MHz bandwidth, 1000MHz platform, easy for upgrade
