LOW NOISE BLOCK
Orbital builds high performance, high quality low noise block downconverters (LNBs) for the satellite communications industry. Our satellite LNBs are available for C, X, Ku and Ka-band. Each unit is expertly engineered, hand-tuned and tested, and comes with specs that are unique to that individual LNB – actual measurements, not averages.
With Orbital, you get the latest technology, very low phase noise, excellent local oscillator (LO) stability and long-term reliability – in the smallest form factor possible.
Our frequency converters are used extensively in military VSAT, SATCOM-on-the-move, emergency services, aeronautical and Earth observation applications. We use only the highest quality components, so our LNBs can seamlessly meet the demands of high throughput satellites (HTS) and produce a consistently flat frequency response. They stand up to Arctic cold, Saharan heat and rainforest humidity – as well as shock, vibration, power surges and static discharge.
What is an LNB?
A low noise block downconverter (LNB) is a small box mounted behind a satellite dish. It receives a satellite signal, amplifies it, and down-converts it to an intermediate frequency (IF) more suited to a modem or receiver. The best LNBs minimize additional phase noise, produce a flat frequency response and offer high performance in a small, ruggedized package.
External Reference, PLL & DRO
Orbital makes three main types of LNBs: external reference, phase-lock loop (PLL) and dielectric resonator oscillator (DRO). If you need low phase noise and maximum data throughput, you need an external reference LNB. PLL is typically used for receiving only, and DRO is used for applications like TV reception, where frequency stability is not crucial.
Need a custom LNB?
Orbital’s engineers can customize everything from bandwidth, signal gain and local oscillator frequency to input/output connectors and DC power options. We can ruggedize our LNBs for airborne use, create multi-band military LNB assemblies, and much more. We have a wealth of experience going back to the ‘70s – so if you have a custom need, we can meet it.
