| ULTRA LOW NOISE PSEUDOMORPHIC HJ FET FEATURES * VERY LOW NOISE FIGURE: NF = 0.6 dB typical at f = 12 GHz * HIGH ASSOCIATED GAIN: GA = 11.0 dB typical at f = 12 GHz * LG = 0.25 m, WG = 200 m Noise Figure, NF (dB) 3 GA NE32400 NOISE FIGURE & ASSOCIATED GAIN vs. FREQUENCY VDS = 2 V, IDS = 10 mA 24 2 18 DESCRIPTION The NE32400 is a pseudomorphic Hetero-Junction FET chip that utilizes the junction between Si-doped AlGaAs and undoped InGaAs to create a two-dimensional electron gas layer with very high electron mobility. This device features mushroom shaped TiAl gates for decreased gate resistance and improved power handling capabilities. The mushroom gate results in lower noise figure and high associated gain for consumer and industrial applications. NEC's stringent quality assurance and test procedures assure the highest reliability and performance. 1.5 15 1 12 0.5 NF 9 0 1 10 20 30 6 Frequency, f (GHz) ELECTRICAL CHARACTERISTICS (TA = 25C) PART NUMBER PACKAGE OUTLINE SYMBOLS NFOPT1 PARAMETERS AND CONDITIONS Optimum Noise Figure at VDS = 2 V, IDS = 10 mA f = 4 GHz f = 12 GHz Associated Gain at VDS = 2 V, IDS = 10 mA f = 4 GHz f = 12 GHz Output Power at 1 dB Gain Compression Point, f = 12 GHz VDS = 2 V, IDS = 10 mA VDS = 2 V, IDS = 20 mA Gain at P1dB, f = 12 GHz VDS = 2 V, IDS = 10 mA VDS = 2 V, IDS = 20 mA Saturated Drain Current at VDS = 2 V, VGS = 0 V Pinch-Off Voltage at VDS = 2 V, IDS = 100 A Transconductance at VDS = 2 V, IDS = 10 mA Gate to Source Leakage Current at VGS = -3 V Thermal Resistance (Channel-to-Case) UNITS dB dB dB dB dBm dBm dB dB mA V mS A C/W 15 -2.0 45 MIN NE32400 00 (CHIP) TYP 0.35 0.6 16.0 11.0 9.5 11.0 11.8 12.8 40 -0.8 60 0.5 10 260 70 -0.2 MAX 0.7 GA1 10.0 P1dB G1dB IDSS VP gm IGSO RTH (CH-C)2 Notes: 1.
