描述 Description

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.

特性 Features

Provides bias for up to three GaAs and HEMT FETsDynamic FET protection and temperature compensationDrain current set by external resistorRegulated negative rail generator requires only 2 external capacitorsAccurate voltage detector and polarisation switch for LNB’s22kHz tone detection for band switching with rejection of unwanted signalsBand switch supports both Discrete, MIMIC and PLL local oscillatorsCompliant with ASTRA control specificationsLow current for power efficient systemsWide operating supply range of 3.3V to 8V

应用 Application

Single Output LNB’sTwo single type twin LNB’sLow power LNB’sPLL Single LNB’s
