The CX2156NLT balun is a device that is designed to resolve impedance imbalance issues in both two-wire and four-wire applications. It is an active balun, created to be used in a wide range of frequency applications. The CX2156NLT is often used in mobile broadcasting and LTE radio systems as it provides an effective link between single-ended signal sources and differential signal paths.

Application Field

The CX2156NLT is designed to be a highly versatile impedance transformers and baluns. It can provide a wide variety of functions, ranging from wideband impedance matching, common mode dynamic range, high rejection of out-of-band signals and antenna matching. The CX2156NLT is ideally suited for applications where high TX to RX isolation is required, such as multi-transmitter mobile wireless broadcast systems, LTE radio systems and antenna systems.The CX2156NLT also has a capability to transform, via frequency tuning, signals from a single ended source to a differential output. This makes the CX2156NLT a highly general active balun, ideal for applications such as mobile broadcast transceivers, base stations and wireless antenna arrays.

Working Principle

The CX2156NLT works on the principle that a single ended signal can be effectively matched and transformed to a differential signal path. This occurs through the use of two RF indicator circuits, one driving the other. The indicator circuits take the single ended input and transform it into a common mode output. This process allows effortless broadband impedance matching, while presenting high TX-RX isolation to out-of-band signals.

The CX2156NLT also features internal protection circuitry to provide protection against electrostatic discharge and reverse power events. This protection helps to ensure that the device remains safe during operation. In addition, the CX2156NLT features a temperature compensation system that helps to maintain the reliability of the device in extreme working conditions.

The CX2156NLT is a highly versatile balun that is able to provide effective impedance matching and transformation in a wide variety of applications. Its ability to provide high TX-RX isolation, along with its internal protection and temperature compensation systems make it a valuable tool for antenna design and wireless broadcast systems.
