The LTC6430-20 operates from a single 5V power supply and consumes only 850m W. In its differential configuration,the LTC6430-20 can directly drive the differential inputs of an ADC. Using 1:2 baluns, the device makes an excellent 50Ω wideband balanced amplifier. While using 1:1.33 baluns, the device creates a high fidelity 40MHz to 1000MHz 75Ω CATV amplifier. The LTC6430-20 is designed for ease of use, requiring a minimum of support ponents. The device is internally matched to 100Ω differential source/load impedance. Onchip bias and temperature pensation ensure consistent performance over environmental changes. The LTC6430-20 uses a high performance Si Ge Bi CMOS process for excellent repeatability pared with similar Ga As amplifiers. All A-grade LTC6430-20 devices are tested and guaranteed for OIP3 at 380MHz. The LTC6430-20 is housed in a 4mm × 4mm, 24-lead, QFN package with an exposed pad for thermal management and low inductance. A single-ended 50Ω IF gain block with similar performance is also...
