SINGLE LNB - COMPLETE BIAS, CONTROL AND POWER MANAGEMENT SOLUTION

Summary

The ZXNB4204 is a single chip power management and control solution for single band satellite Low Noise Blocks (LNB’s). The

highly integrated solution provides all the required FET and mixer bias, control detection and a integrated stable power supply for

the IF amplifiers and additional support functions within the LNB. Packaged ina small 16 pin package the ZXNB4204 only

requires a minimum of 3 external components providing a very small compact solution. Being at the heart of the LNB monitoring

the control, power management and environment conditions, the ZXNB4204 is able to provide reliable solution eliminating

effects such as false switching and over loading. The functionality and the cost effectiveness of this solution makes ZXNB4204

an ideal part for the domestic china market and the other single band applications.
