The ZNBG3115/16 is the core bias and control element of this circuit. The ZNBG provides the negative rail, FET
bias control, polarisation switch control, tone detection and band switching with the minimum of external
components. Compared to other discrete component solutions the ZNBG circuit reduces component count and
overall size required.
APPLICATIONS INFORMATION(cont)
Tone detection and band switching is provided on the ZNBG3115/16 devices. The following diagrams describes
how this feature operates in an LNB and the external components required. The presence or absence of a 22kHz
