Balun

A balun is a transducer that can match two different types of electrical circuits. ，。 These devices are primarily used to connect balanced and unbalanced circuits, for instance between an unbalanced coaxial cable and a balanced dipole antenna. A balun can also be used to connect balanced signals between two pieces of balanced transmission line or to connect unbalanced signals between two pieces of unbalanced transmission line.

CX2032NL balun is a wideband single-ended to differential high linearity balun. It offers excellent performance with excellent return loss, linearity, and spurious freedom. It can operate over the full frequency range from 400 MHz to 4.0 GHz with a typical insertion loss of 0.5 dB and a typical return loss of 18 dB. This balun is designed to deliver excellent electrostatic and mechanical performance as well as good EMI and RFI suppression.

Applications

CX2032NL balun is suitable for a variety of wireless and wired applications including Wireless Local Area Networks (802.11 WLAN), Mobile communications (3G, 4G), WiFi, WiMax, Telemetry, satellite communications, Wireless Sensor Networks (WSN), Automatic Meter Reading (AMR), remote monitoring, CATV, antenna feed systems and more.

Working Principle

The working principle of balun is based on the transformer. It consists of several inductors and transformers that can convert a single-ended signal into a differential signal, or vice versa. The balun transformer uses a series of interconnected inductors to form a balanced line, which reduces the amount of noise and interference in the signal path. Baluns are also used to match the impedance of two different circuits. This helps to reduce the return loss and improve the amount of power that can be transferred between the two circuits.

The CX2032NL balun provides superior matching performance for both single-ended and differential signals. It can handle up to 5 watts of power with a typical insertion loss of 0.5 dB and return loss of 18 dB. The balun is designed to provide excellent power handling and good performance over wide frequency bandwidths, making it suitable for use in many wireless and wired applications.
