Description

A 2:1 combiner is a device used in radio frequency (RF) and microwave systems to combine two input signals into a single output. It's commonly used in wireless communication setups, such as base stations or distributed antenna systems, where signals from two transmitters need to be merged and sent through one antenna. There are two main types: - Passive 2:1 combiners, which use components like transformers or hybrid couplers and don’t require external power. - Active 2:1 combiners, like the LAC-21, which include amplifiers and may offer selectable gain settings to optimize performance. These combiners are designed to maintain signal integrity, minimize insertion loss, and ensure good isolation between input ports. They typically operate across wide frequency ranges—for example, from 698 MHz to 2700 MHz—and are built to handle significant power levels while maintaining impedance matching (usually 50 ohms).
