AT1504

AT1504 Preliminary Product Information FET BIAS CONTROLLER Features ˙Provides bias for GaAs and HEMT FETs ˙Drives up to four FETs ˙Dynamic FET protection ˙Drain current set by external resistor ˙Regulated negative rail generator requires only 2 external capacitors ˙Choice in drain voltage ˙Wide supply voltage range ˙SSOP surface mount package Description The AT1504 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. With the addition of two capacitors and resistors the devices provide drain voltage and current control for a number of external grounded source FETs. The AT1504 is available in SSOP16 pin packages respectively for the minimum in devices size. Device operating temperature is -40 to 70°C to suit a wide range of environmental conditions. Applications ˙Satellite receiver LNBs ˙Private mobile radio (PMR) ˙Cellular telephones Block Diagram Aimtron reserves the right without notice to change this circuitry and specifications. 2F, No.10, Prosperity RD.
