CTB, XMOD, CSO definitions follow NCTA definition ESD PROTECTION Gallium Arsenide Integrated Circuits are sensitive to electrostatic discharge (ESD) and can be damaged by static electricity. Proper ESD control techniques should be used when handling these devices. Some of the precautions recommended are; - Person at a workbench should be earthed via a wrist strap and a resistor. - All mains-powered equipment should be connected to the mains via an earth-leakage switch. - Equipment cases should be grounded. - Relative humidity should be maintained between 40% and 50%. - An ionizer is recommended. - Keep static materials, such as plastic envelopes and plastic trays etc. away from the workbench. ▪ Tel : 82-31-250-5011 ▪ rfsales@rfhic.com ▪ All specifications may change without notice. ▪ Version 5.4 CATV Line Amplifier NOTES FOR CORRECT USE 2F8725P + +24V 47㎌ On the power input port (Pin#5), 47uF/35V capacitor GND is recommended. 2. The heat sink of CATV Hybrids is to be mounted in direct contact with the metal case of the equipment. Heat conducting grease should be applied to the module/equipment interface and the unit tightly secured. 3. Put the power off before adjusting in/output matching of the system. 4. The unit must have a common ground with the equipment and the analyzer. 5. Pay close attention to the input voltage not to over power the hybrid. 6. The space between bottom of socket and the tip of the lead is recommended to have space of 2mm+ to protect the pin 7. Do not open the plastic cover to change the matching inside the hybrid. Once opened, RFHIC will not be responsible for the hybrid. 8. This CATV Hybrid amplifier is designed with GaAs technology and can be damaged by electrical shock. To protect the device from excessive AC input, user should use a high pass filter(Note 1) at the in/output port of the hybrid amp or use a diplexer filter at the in/output port of the system/equipment to be on the safe side. 1.
