Description
|
|
General Description:
The 1RU, 19 inch rack-mount block downconverter assembly
translates RF inputs into IF outputs.
The converters contain
internal crystal controlled, high
stability frequency references. All
crystal oscillators are constantly
powered up so there is no warm up time
when switching to the BDC module. A
splitter provides signal to all BDC
modules (up to four in a single rack),
at once. Non-selected units will have
their local VCO oscillators powered down
to minimize spurious and in-band
interference.
For a
description of our BDC modules, see
Block
Downconverters.

Design
|
|
Orbital Design:
Up to four BDC modules
may be integrated into a single
rack-mount chassis. There are a variety
of choices for the BDC frequency range
within each band: S, C, X, Ku, & Ka.
External Reference
versions are available for C, Ku and Ka
bands only at this time. Enquiries
for X and S band are welcomed.

Power Supplies |
|
Internal/External Power Supplies:
(Optional)
Power supplies,
historically, have the lowest MTBF of
the components in a system. The Orbital
Internal / External power supply
configuration was designed to provide
inexpensive and rapid power supply
replacement. A secondary benefit is the
lower operating temperature of the
external power supply thus extending its
life.
The external power supply
needs to be 24VDC, with a minimum
current rating of 1.2 Amps. It is the
main power supply. If it fails, the
system switches to the internal power
supply. This gives the customer time to
replace the external power supply
without any down time or without having
to take the entire rackmounted chassis
in for repair.

Configurations |
|
BDC Configurations:
Single BDC -
One input, one output.
Dual Wideband
BDCs - Come in two main flavors, either
switch between the modules as in high or
low band or with two outputs (one per
BDC), with both BDCs always on.
Dual Polarity
BDCs - One for each of horizontal and
vertical polarity - both BDCs are always
on.
Dual Polarity,
Dual Wideband - High and Low wideband
BDCs that cover the whole band, and a
second pair to cover both polarities.
Two inputs, four outputs.
Tri Band -
Three BDCs cover the entire band.
Available in switchable single output
and always on (three output) versions.
The above
offerings are available in PLL or
external reference versions, and are
also available in redundant
configurations, either as one for one or
one for two systems.

Orbital
Flexibility:
Engineered
using the highest quality components insures
you from failure due to environmental extremes
such as arctic cold, Saharan heat, and
rain-forest humidity. Our LNB is
protected from man-made conditions such as
chock, vibration, low power, over-voltage,
surges, transients, and static
discharge. Performance is consistent and
replacements will match or exceed your
original device.
"Mass-Custom"
Solution
Orbital
starts with the proven performance product
that is extremely well engineered with the
development costs amortized over thousands of
units and the parts costs reduced by volume
discounts. We then customize the mass
produced DRO LNB into an external reference
version at 1/100 the cost of designing and
building from scratch. |
