The ISL55016 is a high performance gain block which can match a 75Ω single-ended source to a 100Ω differential load. This feature makes the ISL55016 ideal for a wide range of general-purpose applications such as Satellite TV. The ISL55016 can be used as single-ended to differential converter and eliminates the need for an external balun structure.
