Description
Universal amplifier UA 1000 F can be used for broadband distribution of RF signals in CATV
systems in the frequency range 85
-
1000 MHz.
The final stage of the amplifier is designed in GaAs technology. This provides an optimum
relation between
power consumption and channel load.
The amplifier is suitable for distribution of the return path. The use of the return path
(5
-
65 MHz) can be configured by jumpers.
Input and RF output 1 are provided with test sockets (RF output 2 upon request).
Attenu
ation, equalization and other functions can be activated by means of plug
-
in modules.
This guarantees a stable setting during a long period.
The remote power supply is
protected by a self recovering
fuse.
Housing is made of die
-
cast aluminium and offers p
rotection according to IP54. This type of
housing guarantees optimal heat dissipation and perfect protection of the electronic
components.
For optimal HF contact, the
connectors are Cabelcon IEC 14F
-
FF
(at the input) and F

HQ
-1-
01
(at
both outputs). T
he connectors are
mounted with sunken rubber O ring
and soldered inner conductor.
Features
Output splitter included for symmetrical outputs. No additional logistics are needed.
Single output selectable by means of shifting the module one pin to t
he right.
The plug
-
in modules (PIM ..) for attenuation and equalization can be changed without
service interruption.
No power consumption in returnpath amplifier when disabled.
Ultra
-
high efficiency switch mode power supply (> 88%).
Indicator for DC and AC
supply voltages enabling fast diagnosis.
Power factor corrector which reduces power loss in feeding
-
net by 75% (I²R).
Ceramic capacitors in switch mode power supply secondary site, significantly
improving lifetime, reliability and EMI.
Only electrolytic
capacitor on input site, stress protected by PFC.
