LTC6430AIUF-15#PBF

射频放大器芯片, 15.2 DB 增益, 20 MHz 至2 GHz, 4.75 V- 5.25 V, 800 mW, QFN-24

The is a high linearity differential RF/IF Amplifier/ADC Driver designed to drive high resolution, high speed ADCs with excellent linearity beyond 1000MHz and with low associated output noise. The LTC6430-15 operates from a single 5V power supply and consumes only 800mW. In its differential configuration, theLTC6430-15 can directly drive the differential inputs of an ADC. Using 1:2 baluns, the device makes an excellent 50R wideband balanced amplifier. While using 1:1.33 baluns, the device makes a high fidelity 50 to 1000MHz 75R CATV amplifier. The LTC6430-15 is designed for ease of use, requiring a minimum of support components. The device is internally matched to 100R differential source/load impedance. On chip bias and temperature compensation ensures consistent performance over environmental changes. The LTC6430-15 uses a high performance SiGe BiCMOS process for excellent repeatability compared with similar GaAs amplifiers.
