ZXNB4204
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.
