ZXNB4204 Datasheet | Diodes Incorporated

CONFIDENTIAL A Product Line of Diodes Incorporated SINGLE LNB - PLETE 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 ponents providing a very small pact 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.
