The ZNBG3118 is a bias and control solution designed for Satellite Low Noise Blocks (LNB’s). Providing three bias stages to
power control and protect the GaAs or HEMT FET low noise amplifier’s (LNA’s). The ZNBG3118 integrates an accurate voltage
detector to select the LNB polarisation channel and an advanced tone detector to select the local oscillator (LO) for band
switching.
