CATV Line Amplifier
2F8727P
NOTES FOR CORRECT USE
1. 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.
