| NEC's C TO KA BAND SUPER LOW NOISE AMPLIFIER N-CHANNEL HJ FET CHIP FEATURES * SUPER LOW NOISE FIGURE: 0.45 dB TYP at 12 GHz * HIGH ASSOCIATED GAIN: 12.5 dB TYP at 12 GHz m * GATE LENGTH: LG = 0.20 * GATE WIDTH: WG = 200 m 89 25 13 Drain NE32500 OUTLINE DIMENSIONS (Units in m) CHIP 58 5.5 36.5 13 66 25 38 68 DESCRIPTION NEC's NE32500 is a Hetero-Junction FET chip that uses the junction between Si-doped AlGaAs and undoped InGaAs to create very high mobility electrons. Its excellent low noise figure and high associated gain make it suitable for commercial systems and industrial applications. NEC's stringent quality assurance and test procedures assure the highest reliability and performance. 350 76.5 Source Source 100.5 Gate 21 25 25 13 66 49.5 43 350 60 46.5 Thickness = 140 m Bonding Area ELECTRICAL CHARACTERISTICS (TA = 25C) PART NUMBER PACKAGE OUTLINE SYMBOLS NF GA IDSS gm IGSO VGS(off) RTH (CH-C) PARAMETERS AND CONDITIONS Noise Figure, VDS = 2 V, IDS = 10 mA, f = 12 GHz Associated Gain, VDS = 2 V, IDS = 10 mA, f = 12 GHz Saturated Drain Current, VDS = 2 V,VGS = 0 V Transconductance, VDS = 2 V, ID = 10 mA Gate to Source Leakage Current, VGS = -3 V Gate to Source Cutoff Voltage, VDS = 2 V, ID = 100 A Thermal Resistance1 (Channel to Case) UNITS dB dB mA mS A V C/W -0.2 11.0 20 45 MIN NE32500 00 (Chip) TYP 0.45 12.5 60 60 0.5 -0.7 10.0 -2.0 260 90 MAX 0.55 Note: 1.
