DEVICE DESCRIPTION

The ZLNB101 dual polarisation switch controller is one of a wide range of satellite receiver LNB support circuits. It features two completely independent channels, each providing two logic outputs under the control of a voltage sensitive input. It is intended for use in Twin LNB designs, replacing many dIscrete components to save both manufacturing cost and PCB size whilst improving reliability.
