UTC X3211 LINEAR INTEGRATED CIRCUIT
FET BIAS CONTROLLER WITH
POLARISATION SWITCH AND TONE
DETECTION
DESCRIPTION
The UTC X3211 is designed to meet the bias requirements
of GaAs and HEMT FETs commonly used in satellite receiver
LNBs, PMR, cellular telephones etc. with a minimum of
external components.
FEATURES
* Provides bias for GaAs and HEMT FETs
* Drives up to three FETs
* Dynamic FET protection
* Drain current set by external resistor
* Polarisation switch for LNBs –supporting zero volt gate
switching topology.
* 22kHz tone detection for band switching
APPLICATIONS
*Satellite receiver LNBs
* Private mobile radio (PMR)
* Cellular telephones
