EHF-FD1620

Baluns are electrical devices, also known as impedance transformers, which are used to connect two different types of circuits. The EHF-FD1620 balun is a high-frequency radio-frequency (RF) balun, designed to provide a 50 ohm matched impedance transformation from a 75 ohm system or vice versa. This type of balun is perfect for applications like digital TV and satellite receivers, radio transceivers, repeaters, ASI signal converters, and any other application requiring high performance RF impedance matching and signal conversion. It offers low insertion loss, high output power handling and low drifting.

The EHF-FD1620 balun is capable of operating in the frequency range from 3 MHz up to 18 GHz, with an input impedance of 75 ohms and output impedance of 50 ohms. Its operation is based on a principle where the input signal is converted to a high-impedance balanced output signal. This is achieved by differential-mode line transformation, along with an appropriate matching network. The differential-mode line transformation is a technique that takes an unbalanced input signal, and proceeds to convert it to a balanced, full differential output signal by using two separable transformers. These transformers operate in opposition to one another in order to cancel out the common-mode signal, resulting in a differential-mode output signal.

The EHF-FD1620 balun is manufactured using high quality components, including RF transformers and capacitors, along with an integrated capacitor network. This provides optimal noise rejection and impedance conversion. The design also incorporates an innovative \'mini-smoke\' shield technique which helps to ensure the reliability of the balun under extreme hot and humid environmental conditions.

The EHF-FD1620 balun is suitable for several different applications, including: digital TV and satellite receivers, radio transceivers, repeaters, ASI signal converters and other applications requiring high-performance RF impedance matching and signal conversion. Additionally, the balun can be used for cable TV systems, telecom infrastructures and base stations, power network formations, and other RF transmission systems requiring high-impedance isolation. It is also suitable for broadband and coaxial cable systems which require a low VSWR (Voltage Standing Wave Ratio).

In conclusion, the EHF-FD1620 balun is a reliable and high-performance balun which is perfect for applications that require high-impedance isolation, along with excellent signal conversion and impedance matching. Its differential-mode line conversion, along with the integrated capacitor network, ensures exceptional noise rejection and reliable operation in a wide variety of applications.
