LOW NOISE BLOCK
Orbital Research 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 a datasheet that is unique to that individual LNB – actual measurements, not averages.
With Orbital LNBs, you get the latest technology for your satellite terminal, very low phase noise, excellent local oscillator (LO) stability, consistent linearity, and long-term reliability – in a small and lightweight package.
Our LNBs 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. We can also customize our LNBs to meet any requirement.

Now more than ever, reliable satellite communications are crucial – helping military and emergency teams respond to those in need around the world, including those affected by COVID-19. For journalists reporting from the front lines, airlines providing WIFI for essential medical workers, and SATCOM-on-the-move customers supporting FEMA, satellite communications are vital for both safety and productivity.
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.
