| E2Q0055-18-73 electronic components This version: Jul. 1998 Previous version: -- KGF1265 electronic components KGF1265 Medium-Power Amplifier GENERAL DESCRIPTION The KGF1265 is a medium-power amplifier, with frequencies ranging from the UHF-band, that features high output power, low distortion, and low current operation. The KGF1265 specifications are guaranteed to a fixed matching circuit for 3 V and 900 MHz band; external impedancematching circuits are also required. Because of the high output power and low distortion at the low operating current, the KGF1265 is ideal as a transmitter-driver amplifier for portable phones such as PDC and CDMA. FEATURES * High output power: 11 dBm (min.) * Low voltage and low current operation: 3 V, 18 mA (max.) * Low distortion (ACP): -55 dBc (max) @PO = 8dBm, p/4DQPSK, 50 kHz * 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) 1/9 electronic components KGF1265 MARKING (4) (3) NXX (1) (2) NUMERICAL NUMERICAL PRODUCT TYPE LOT NUMBER (1) Gate (2) Source (3) Drain (4) GND CIRCUIT Drain(3) Gate(1) Source(2) GND(4) 2/9 electronic components KGF1265 ABSOLUTE MAXIMUM RATINGS Item Drain-source voltage Gate-source voltage Drain current Total power dissipation Channel temperature Operating temperature Storage temperature Symbol VDS VGS IDS Ptot Tch Tope Tstg Condition Ta = 25C Ta = 25C Ta = 25C Ta = 25C -- -- -- Unit V V mA mW C C C Min. -- -3.0 -- -- -- -35 -45 Max. 8 0.4 28 200 150 85 125 ELECTRICAL CHARACTERISTICS Item Frequency Operating current Linear gain Output power Adjacent Channel Power 1 Adjacent Channel Power 2 Noise figure Symbol f ID GLIN PO ACP1 ACP2 F (*1), PIN = 0 dBm (*1), PIN = -20 dBm (*1), PIN = 0 dBm (*1), PO = 8 dBm, 50 kHz offset (*1), PO = 8 dBm, 100 kHz offset (*1) Condition Unit MHz mA dB dBm dBc dBc dB Min. 889 -- 13.0 11.0 -- -- -- Typ. -- -- 15.0 12.5 -60 -70 -- (Ta = 25C) Max. 960 18.0 -- -- -55 -65 3.0 *1 Self-bias condition: VDD = 3 V, VG = 0 V 3/9 electronic components KGF1265 RF CHARACTERISTICS 4/9 electronic components KGF1265 5/9 electronic components KGF1265 6/9 electronic components Typical S Parameters KGF1265 VDD = 3 V 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 0.915 0.862 0.813 0.770 0.735 0.708 0.686 0.668 0.662 0.655 0.654 0.655 0.657 0.665 0.673 0.679 0.686 0.691 0.698 0.703 0.706 0.706 0.710 0.711 0.711 0.710 -54.66 -65.63 -75.40 -85.38 -93.08 -102.19 -110.12 -117.86 -123.89 -130.53 -136.56 -141.96 -147.69 -152.50 -157.31 -162.17 -166.90 -171.49 -175.91 179.67 175.24 170.85 166.54 162.28 158.25 153.79 4.476 4.351 4.134 3.986 3.699 3.565 3.386 3.244 3.032 2.870 2.732 2.563 2.454 2.297 2.157 2.062 1.939 1.831 1.728 1.644 1.528 1.466 1.354 1.297 1.192 1.145 128.63 117.04 107.13 97.98 89.86 82.40 74.99 68.15 62.32 55.64 49.96 44.30 38.52 33.19 28.11 22.74 17.68 12.95 8.07 3.82 -1.22 -5.08 -8.96 -13.82 -16.22 -20.50 0.062 0.059 0.057 0.056 0.054 0.054 0.053 0.055 0.058 0.063 0.070 0.079 0.089 0.099 0.112 0.125 0.139 0.151 0.166 0.177 0.195 0.204 0.219 0.229 0.242 0.254 33.24 30.50 29.69 30.85 33.11 36.50 42.10 47.65 54.31 59.01 63.77 66.59 68.50 69.01 68.50 67.98 66.28 64.42 61.90 59.48 56.31 53.81 50.11 47.47 43.57 41.41 0.598 0.531 0.492 0.469 0.455 0.453 0.451 0.459 0.466 0.479 0.492 0.509 0.525 0.545 0.563 0.582 0.599 0.617 0.634 0.649 0.661 0.675 0.683 0.694 0.700 0.707 -76.25 -85.34 -92.80 -99.26 -106.30 -111.84 -117.81 -123.09 -128.56 -133.39 -138.40 -142.96 -147.66 -152.30 -156.46 -161.01 -165.29 -169.54 -173.69 -178.01 177.84 173.58 169.29 164.93 160.94 156.55 7/9 electronic components Typical S Parameters KGF1265 VDD = 3 V Frequency : 0.5 to 3.0 GHz Z0 = 50 W 8/9 electronic components Test Circuit (VDD = 3 V, f = 889 MHz to 960 MHz) KGF1265 KGF1265 100pF RF IN 5pF 510W 2 10nH 1 4 VDD N12 68nH 100pF 12nH 4pF RF OUT 3 OPEN 9/9 |
