Orbital Research bias tees and diplexers seamlessly interconnect indoor and outdoor SATCOM equipment – modems, low noise block downconverters (LNBs), low noise amplifiers (LNAs) and block upconverters (BUCs) – from disparate manufacturers. In addition to injecting external DC current, these RF components provide signal multiplexing and demultiplexing, DC extraction, L-band and 10 MHz filtering and more.

Our bias tees (also called bias Ts) can be customized to your needs. Built primarily for the satellite communications industry – but also used by 4G and 5G cellular network operators – these unique RF components offer very low thru loss and exceptionally high return loss performance.

Learn about Orbital bias tees – including our best-selling Mux-Tee (a bias tee and 10 MHz multiplexer) and thru tees (bias tee “thruplexers” that filter L-band and 10 MHz signals).
