VGO 939-1G/VGF 939-1G

The compact amplifier with
slide switches –
VGO 939-1G/VGF 939-1G

In addition to the devices with electronic setting,
Kathrein offers yet another highly innovative
compact amplifier platform. This particularly
economical series requires no equaliser cards
or attenuation pads. All adjustments can be easily
carried out using slide switches.

Simple, yet effective

The required attenuation and slope values are
set with a combination of several slide switches.
The advantages are obvious. Besides saving
plug-in cards, this allows exact reproduction of
setting values without requiring a measuring
instrument.
Replacement of the device, for example, is thus
much easier.

When slide switches are shifted, a virtually uninter-
rupted signal flow is guaranteed – multimedia
services remain undisturbed.

Maximum reliability

The implemented slide switches fulfil the highest
demands regarding reliability and endurance.
Dual gold-plated contact reeds, increased
contact pressure and a separate catch spring
ensure ultimate reliability of the switches, which
have been proven and tested 100,000 times.

• Latest GaAs-MMIC technology
• Innovative operational concept:

- Settings via slide switches
- Device settings can be reproduced exactly
- Fewer plug-in cards and variable attenuators
needed

• Integrated diplexers allow optimised data
• Very high output level at lowest intermodulation

products (also for interstage attenuation)

• Pluggable loop-through output
• One or two output(s) configurable
• Built-in active return path with various setting

possibilities

• Return path can also be operated passively
• 15 MHz high pass can be activated in the

return path

• Ingress Control Switch (ICS)
• Monitorable with HMS or DOCSIS transponder

(option)

• Insert position for additional functions in the

forward path (e.g. de-emphasis)

• Bi-directional test socket on the amplifier input
• Directional coupler test socket on amplifier output

and in return path

• Test signals can be coupled in for the return path
• LED as function indicator
• Highly efficient switched-mode power supply unit
• Advanced remote power concept in the

VGF 939-1G:

Newly developed remote feed coils
Remote feed current: Max. 7 A per connec-
tion, local insertion max. 10 A totally

local insertion max. 10 A totally

Remote feeding possibilities: By choice via
all RF connections or local connector

• Surge absorber on all RF connections and in

switched-mode power supply unit

• Power management: Unused amplifier stage

switch-off for reduced power consumption

• Die-cast housing with PG 11 connectors
• Easy connection of large cable fittings due to

extended thread distance

• Outdoor operation possible, housing protection

class: IP 54

• Test sockets: F-type connectors (internal)
