Well, first it should meet the higher standards of industrial as opposed to consumer use.  Secondly, it should have some kind of qualification; and the the qualification of each of these LNBs is printed on each label.  The unique, measured, performance test of each individual LNB is on the label.  How else will you know what you are really getting?

With a single LNA covering the whole band, you can cover from 10.7 to 12.75 GHz with just two Orbital BDCs, 10.7~11.7 GHz and 11.7~12.75 GHz - or you can stack the output of two 500 MHz B/W polarities into one combined L band output: 950~1450 MHz and 1500~2000 MHz

Why Would I Need a BDC?

Block Downconverters are used when you want to cover the entire band with a single antenna.  All you need is an LNA that covers the entire bandwidth of the satellite, then order Orbital BDC modules that cover the specific sections of the band that you need.

Redundancy You Can't Afford to Be Without

The most common type of system failure is the failure of a power supply.  The least expensive form of redundancy is the Orbital Dual Power Tee which has all of the features of the Orbital Bias Tee plus dual DC inputs.

Why a Ka External Reference DRO?

Phase lock loop designs double phase noise as well as drift when they are raised to Ka frequencies.  However, DRO designs maintain low phase noise while drift is eliminated through the use of an External Reference.  Orbital is proud to introduce the phase locked DRO Ka external reference LNB.  

You need a higher power BUC, but your modem cannot supply adequate DC...

You need a bias tee and a separate power supply.  But conventional Bias Tees shunt the 10 MHz reference signal to AC ground.  You could use the MT25/40 Orbital Mux/Tee, if you have a separate 10 MHz signal, but your modem only supplies 10 MHz up the cable with the L band signal.  The excellent MT1 filters the L band, stopping the 10 MHz signal from passing through.

In satellite applications there are three distinct signals linking the LNB/BUC, the receiver/modem, the power supply, and the 10 MHz external reference oscillator.  These signals have to move on the same wire and not interfere with each other.  These signals have enormously different amplitudes, frequencies, and bandwidths.

Many of the world's largest satellite businesses use Orbital's Systems Interface Products to insert, extract, mux, filter, amplify, combine, divide, and switch their signals.  We also build conversion systems that use our BDCs and LNBs in conjunction with SIP Products to provide integrated down-conversion systems.

The four circumstances for defining stability are as follows:

1. Stability at an instant
2. Stability at a given temperature
3. Stability over a range of temperatures
4. Stability over a long period of time

The Orbital MY25/40 Mux Tee can insert or extract the 10 MHz reference signal, it can be used to insert or extract DC.  It can be used as a Bias Tee, as a Mux Tee, or as a Diplexer.  You can have a choice of connectors, it filters and conditions signals, and it can perform L band impedance transforms.

Redundancy is about a system surviving disaster, such as a lightning strike or failure in a complex component.  Most redundant systems only switch to a backup LNB or BDC on a change in current consumption.  Sometimes though, a failure in an LNB or BDC doesn't result in a change in current consumption...

You use a Combiner when you want to add another service without adding another system.  With a Orbital Combiner, you can add a second modem or receiver without having to add an additional system.  You can use the existing antenna and cabling - a significant saving in equipment, labor, and civils costs.

You don't have to pay a fortune to have superb, professional quality BDCs.   With an LNA that covers your satellite, simply order a custom Orbital BDC to cover the bandwidth that you need.  You can specify input and output connector types, external DC input, coaxial DC input, or dual power option.  Most importantly, we can customize your gain to optimize compression point and noise distribution.  Just tell us your needs, and we will build a mass-custom solution in a unique, cost effective way.
