ZNBG3118 Datasheet (Zetex Semiconductors) - A Flexible Bias And Control Solution

ZNBG3118, A Flexible Bias And Control Solution

The ZNBG series of devices are designed to meet the bias requirements of GaAs and HEMT FETs commonly used in satellite receiver LNBs with a minimum of external components.

With the addition of two capacitors and a resistor the devices provide drain voltage and current control for three external grou

A Product Line of Diodes Incorporated ZNBG3118 LNA GaAs FET BIAS CONTROLLER WITH POLARIZATION AND BAND SELECT Summary 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.
