Orbital Ku-Band Professional Series BDCs

Orbital Block Down Converters

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.

Orbital Flexibility

With an LNA that covers your satellite, simply order a custom Orbital BDC to cover the bandwidth that you need. You can even cover from 10.7 to 12.75 with just two Orbital BDCs. Or stack the output: 950 to 2000. Specify input and output connector types, and 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.

“Mass-Custom” Solution

Orbital starts with a proven performance product that is extremely well engineered with the development costs amortized over hundreds of thousands of units and the parts costs reduced by volume discounts. We then customize the mass produced LNB into what you want at 1/100 the cost of designing and building from scratch.

Enhancing Standard Product

Mass-production means low-cost, reliable,repeatable products. Engineers designthese products well within margins oncomponent specifications so thatindividual tuning is not required to meetdesired specifications.

As we modify product, we also tweak thedesign and components to optimize themfor their inherent capabilities. Effectively,we bring out the full potential of theproduct by adjusting components to theirfull capability.

Loss of Lock Alarm – LOLA (optional)

LNBs can lose oscillator lock from internal failure or loss of the 10 MHz reference. The LOLA detects this anomaly and increases the current consumption of the LNB over the IFL cable to trigger a redundant switch or other detector. No extra ports, cables or infrastructure are required.

Simply hookup the LNB with 10 MHz present, set the current windows on the redundancy system so they are just out of triggering, then turn off the 10 MHz to trigger the LNB LOL circuit. The redundant switch should activate. Restore 10 MHz and the LOLA will reset.

It should be noted that these LNBs are exceptionally good for 10 MHz lock range. They will stay locked under adverse 10 MHz conditions and keep the system in sync.

BDC Solutions

The term BDC is commonly used to refer to the modules (which look like an LNB with the waveguide removed and replaced with a connector), and to the rack-mounted unit which might contain from one to several BDC modules. BDCs are increasingly used in outdoor units at the antenna - ODUs, and have an indoor rack mounted controller - IDUs. BDCs are commonly used when a client uses multiple BDCs and a single LNA to cover the entire band.
