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.
