A Product Line of Diodes Incorporated ZXNB4202 SINGLE LNB - COMPLETE BIAS, CONTROL AND POWER MANAGEMENT SOLUTION Summary The ZXNB4202 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 package the ZXNB 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 ZXNB4202 is able to provide reliable solution eliminating effects such as false switching and over loading.
