The ZXNB4202 is a single chip power management and control solution for satellite Low Noise Blocks (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 amplifiers and additional support functions.Packaged in a small 16 pin package the ZXNB4202 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 environmental conditions, the ZXNB4202 is able to provide reliable solution eliminating effects such as false switching and over loading.


  • Single chip LNB bias, control and power management
