| E2Q0038-38-72 electronic components This version: Jul. 1998 Previous version: Jan. 1998 KGF1321S electronic components KGF1321S Power FET (Ceramic Package Type) GENERAL DESCRIPTION The KGF1321S, housed in a SMD-type ceramic package, is a discrete UHF-band power FET that features high efficiency, high output power, and low current operation. The KGF1321S specifications are guaranteed to a fixed matching circuit for 5.8 V and 850 MHz; external impedance-matching circuits are also required. Because of its high efficiency, high output power (more than 31.5 dBm), and SMD package, the KGF1321S is ideal as a transmitter-final-stage amplifier for personal handy phones, such as analog cellular phones. FEATURES * High output power: 31.5 dBm (min.) * High efficiency: 70% (min.) * Low thermal resistance: 18C/W (typ.) * Package: 3PFP 1/7 electronic components KGF1321S MARKING (1) (2) K1321S XXXX PRODUCT NAME LOT NUMBER MONTHLY LOT NUMBER (3) PRODUCTION MONTH (1-9,X,Y,Z) PRODUCTION YEAR (LOWEST DIGIT) (1) Gate (2) Source (3) Drain CIRCUIT Drain(3) Gate(1) Source(2) 2/7 electronic components KGF1321S ABSOLUTE MAXIMUM RATINGS Item Drain-source voltage Gate-source voltage Drain current Total power dissipation Channel temperature Storage temperature Symbol VDS VGS IDS Ptot Tch Tstg Condition Ta = 25C Ta = 25C Ta = 25C Ta = Tc = 25C -- -- Unit V V A W C C Min. -- -6.0 -- -- -- -45 Max. 10 0.4 3 5 150 125 ELECTRICAL CHARACTERISTICS Item Gate-source leakage current Gate-drain leakage current Drain-source leakage current Drain current Gate bias Q-point Output power Drain efficiency Thermal resistance Symbol IGSS IGDO IDS(off) IDSS VGSQ PO hD Rth Condition VGS = -6 V VGD = -16 V VDS = 10 V, VGS = -6 V VDS = 1.5 V, VGS = 0 V VDS = 5.8 V, IDSQ = 175 mA (*1), PIN = 20 dBm (*1), PIN = 20 dBm Channel to case Unit mA mA mA A V dBm % C/W Min. -- -- -- 2.0 -3.35 31.5 70 -- Typ. -- -- -- -- -- -- -- 18 (Ta = 25C) Max. 0.1 0.5 1.5 -- -2.45 -- -- -- *1 Condition: f = 850 MHz, VDS = 5.8 V, IDSQ = 175 mA 3/7 electronic components KGF1321S CHARACTERISTICS 4/7 electronic components Typical S Parameters KGF1321S VDS = 5.8 V, IDS = 175 mA Freq(MHz) MAG(S11) ANG(S11) MAG(S21) ANG(S21) MAG(S12) ANG(S12) MAG(S22) ANG(S22) 500.0 600.0 700.0 800.0 900.0 1000.0 1100.0 1200.0 1300.0 1400.0 1500.0 1600.0 1700.0 1800.0 1900.0 2000.0 2100.0 2200.0 2300.0 2400.0 2500.0 2600.0 2700.0 2800.0 2900.0 3000.0 0.934 0.933 0.931 0.933 0.930 0.929 0.928 0.926 0.926 0.923 0.923 0.922 0.917 0.920 0.914 0.915 0.911 0.911 0.908 0.907 0.907 0.902 0.900 0.898 0.899 0.894 -147.47 -153.34 -157.83 -161.16 -164.05 -166.41 -168.49 -170.28 -171.90 -173.38 -174.79 -176.22 -177.31 -178.52 -179.85 179.28 177.85 176.88 175.84 174.63 173.85 172.51 171.60 170.55 169.48 168.51 3.870 3.279 2.828 2.511 2.240 2.030 1.857 1.707 1.592 1.473 1.389 1.302 1.236 1.173 1.109 1.066 1.012 0.976 0.937 0.899 0.866 0.838 0.808 0.790 0.753 0.740 96.34 91.79 87.72 84.05 81.08 77.97 75.35 72.50 69.75 67.32 64.77 62.62 60.10 57.77 55.53 53.31 51.00 49.02 46.71 44.87 42.33 40.77 38.27 36.48 34.27 32.15 0.038 0.039 0.040 0.041 0.041 0.042 0.042 0.043 0.043 0.044 0.045 0.045 0.046 0.046 0.047 0.048 0.048 0.049 0.050 0.050 0.051 0.051 0.053 0.053 0.054 0.054 21.91 19.84 18.53 17.91 17.58 16.76 16.78 16.71 16.93 16.46 16.93 16.32 17.35 17.04 16.94 17.25 16.74 16.78 17.16 16.68 17.70 16.95 17.15 17.33 17.22 17.56 0.666 0.671 0.674 0.674 0.678 0.678 0.677 0.678 0.677 0.679 0.675 0.678 0.676 0.678 0.676 0.676 0.674 0.677 0.673 0.674 0.674 0.675 0.673 0.674 0.675 0.673 -175.31 -176.79 -177.80 -178.81 -179.43 179.49 179.10 178.16 177.44 176.95 176.29 175.63 175.18 174.46 173.46 173.10 172.11 171.75 170.74 170.18 169.41 168.69 167.92 167.17 166.38 165.56 5/7 electronic components Typical S Parameters KGF1321S VDS = 5.8 V, IDS = 175 mA Frequency : 0.5 to 3.0 GHz Z0 = 50 W 6/7 electronic components KGF1321S PACKAGE DIMENTIONS 1.10.2 0.510.15 0.50.05 4.40.15 1.90.15 3.00.15 6.30.15 2.80 3.70.15 1.50.15 0.1250.05 3.80.15 3.50.15 2.0 2.05 2.85 METALIZATION (Unit: mm) Package material Lead frame material Pin treatment plate thickness Al203 Fe-Ni-Co alloy Ni/Au plating Au:1.0 mm or more 3.4 5.6 MAX 4.20.15 7/7 |
