Its excellent low noise and high associated gain make it suitable for TVRO and other commercial systems. 8 4 1 2 4 6 8 10 14 20 30 Frequency, f (GHz) RECOMMENDED OPERATING CONDITIONS SYMBOLS VDS ID PIN CHARACTERISTIC Drain to Source Voltage Drain Current Input Power (TA = 25C) UNITS MIN TYP MAX V mA dBM 2 15 2.5 20 0 ELECTRICAL CHARACTERISTICS (TA = 25C) NE434S01 S01 UNITS A mA V mS dB dB 13.0 20 -0.2 70 MIN TYP 0.5 80 -0.9 85 0.35 15.5 0.45 MAX 10 150 -2.5 PART NUMBER PACKAGE OUTLINE SYMBOLS IGSO IDSS VGS(off) gm NF1 GA1 PARAMETERS AND CONDITIONS Gate to Source Leak Current, VGS = -3.0 V Saturated Drain Current, VDS = 2.0 V, VGS = 0 V Gate to Source Cutoff Voltage, VDS = 2.0 V, ID = 100 A, Transconductance, VDS = 2.0 V, ID = 14 mA Noise Figure, VDS = 2.0 V, ID = 15 mA, f = 4 GHz Associated Gain, VDS = 2.0 V, ID = 15 mA, f = 4 GHz Note: 1. Typical values of noise figures and associated gain are those obtained when 50% of the devices from a large number of lots were individually measured in a circuit with the input individually tuned to obtain the minimum value. Maximum values are criteria established on the production line as a "go-no-go" screening tuned for the "generic" type but not each specimen.
