UNISONIC TECHNOLOGIES CO., LTD L8200 LINEAR INTEGRATED CIRCUIT SINGLE LNB-BIAS, CONTROL AND POWER MANAGEMENT SOLUTION  DESCRIPTION The UTC L8200 is a single chip power management and control solution for LNB’s. The highly integrated solution provides all the required FET and mixer bias, control detection and decoding, local oscillator switching and a stable power supply for the IF amplifier, and additional support functions. Packaged in a small 16 pin QFN package or 16 pin TSSOP package the UTC L8200 only requires 3 external components providing a very small compact solution. Being at the heart of the LNB monitoring the control, power management and environmental conditions the UTC L8200 is able to provide reliable solution eliminating effects such as false switching and over loading.
