| E2Q0021-38-72 electronic components This version: Jul. 1998 Previous version: Jan. 1998 KGF1181B electronic components KGF1181B Medium-Power Amplifier GENERAL DESCRIPTION The KGF1181B is a two-stage medium-power UHF-band amplifier that features high gain, high output power, and low power operation. The internally matched 50 W input and output eliminate external impedance-matching circuits. All specifications for this device are guaranteed at 5 V and 850 MHz. Because of the high gain and high output power, the KGF1181B is ideal as a transmitter-intermediate-stage amplifier for personal handy phones. FEATURES * Internally matched 50 W input and output * High linear gain: 20 dB (min.) * High output power: 11.5 dBm (min.) * Low current operation: 40 mA (max.) * Self-bias circuit configuration with built-in source capacitor * Package: 4PSOP PACKAGE DIMENSIONS 1.80.1 0.850.05 0.6 +0.1 -0.05 0.4 +0.1 -0.05 1.10.15 0.36 0.74 3.00.2 1.50.15 0.3 MIN 0 to 0.15 Package material 1.90.1 2.80.15 Lead frame material 0.125 +0.03 -0 Epoxy resin 42 alloy Solder plating 5 mm or more Pin treatment Solder plate thickness (Unit: mm) 1/8 electronic components KGF1181B MARKING (4) (3) CXX (1) (2) NUMERICAL NUMERICAL PRODUCT TYPE LOT NUMBER (1) IN (2) VD1 (3) OUT (4) GND CIRCUIT VD1(2) Cf Rf IN(1) Q1 RS1 RG1 CS1 GND(4) RG2 CS2 Q2 RS2 CC OUT(3) 2/8 electronic components KGF1181B ABSOLUTE MAXIMUM RATINGS Item Supply voltage Input power Total power dissipation Channel temperature Storage temperature Symbol VDD PIN Ptot Tch Tstg Conditions Ta = 25C Ta = 25C Ta = 25C -- -- Unit V dBm mW C C Min. -- -- -- -- -45 Max. 10 6 300 150 125 ELECTRICAL CHARACTERISTICS (Ta = 25C) Item Operating current Linear gain Output power Input return loss Symbol ID GLIN PO RLIN Conditions (*1), PIN = 0 dBm (*1), PIN = -20 dBm (*1), PIN = 0 dBm (*1), PIN = -20 dBm Unit mA dB dBm dB Min. -- 20.0 11.5 -- Typ. -- -- -- -18.0 Max. 40.0 -- -- -- *1 Self-bias condition: VDD = 5.2 V, f = 850 MHz 3/8 electronic components KGF1181B RF CHARACTERISTICS 4/8 electronic components KGF1181B 5/8 electronic components Typical S Parameters KGF1181B VDD = 5 V, ID = 25.5 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 0.225 0.194 0.160 0.128 0.099 0.078 0.079 0.099 0.122 0.143 0.162 0.173 0.182 0.189 0.192 0.196 0.197 0.196 0.195 0.192 0.195 0.193 0.194 0.195 0.196 0.198 -73.96 -83.51 -95.59 -113.58 -139.96 -176.28 140.16 109.32 88.58 72.45 61.99 52.98 45.27 39.56 34.22 29.98 25.53 21.33 17.92 14.26 11.84 8.31 6.31 4.04 0.81 -1.35 10.928 11.264 11.461 11.551 11.432 10.984 10.295 9.320 8.398 7.362 6.483 5.707 5.011 4.435 3.942 3.512 3.158 2.856 2.580 2.347 2.131 1.960 1.796 1.661 1.535 1.424 -34.12 -46.61 -59.58 -73.18 -87.52 -102.34 -116.91 -130.65 -143.34 -154.70 -164.55 -173.40 178.69 171.29 164.86 158.67 153.01 147.49 142.39 137.60 133.02 128.32 124.09 119.21 115.25 110.74 0.018 0.023 0.028 0.033 0.038 0.043 0.046 0.051 0.053 0.056 0.058 0.061 0.063 0.064 0.068 0.070 0.073 0.075 0.079 0.081 0.086 0.089 0.093 0.096 0.099 0.103 93.77 91.50 88.67 86.61 81.86 77.98 74.33 69.99 67.04 65.05 63.02 61.23 60.52 57.80 58.14 57.52 56.93 55.36 55.00 55.69 53.68 52.40 50.34 49.57 49.19 47.80 0.391 0.350 0.305 0.259 0.211 0.180 0.179 0.210 0.246 0.284 0.314 0.340 0.356 0.372 0.381 0.390 0.401 0.405 0.411 0.412 0.418 0.423 0.428 0.438 0.445 0.455 -61.62 -72.91 -87.74 -106.94 -133.79 -168.49 152.13 120.21 96.42 79.27 66.56 56.49 48.34 41.34 35.18 29.57 24.62 20.51 16.27 12.62 9.36 5.63 2.81 -0.43 -2.91 -6.22 6/8 electronic components Typical S Parameters KGF1181B VDD = 5 V, ID = 25.5 mA Frequency : 0.5 to 3.0 GHz Z0 = 50 W 7/8 electronic components KGF1181B Test Circuit and Bias Configuration for KGF1181B Feed through Capacitor 1000 pF 1000 pF 200 W (2) IN DC Block 1000 pF 50 W Line (1) KGF 1181B VDD = 5 V ,, + - (3) Choke Coil 60 nH (4) DC Block 1000 pF 50 W Line 10 mF OUT Test Circuit Board for KGF 1181B Substrate : Glass-epoxy resin ( 0.8 mmt,18 mt Cu plated both side, er=4.8 ) 8/8 |
