| E2Q0046-38-71 electronic components This version: Jul. 1998 Previous version: Jan. 1998 KGF2702 electronic components KGF2702 Wide-Band Amplifier GENERAL DESCRIPTION The KGF2702, housed in an 8-pin SOP plastic package, is a two-stage amplifier that features flat and high gain over a wide range of frequencies, internal input and output matching, and high output power. The internally matched 50 W input and output eliminate external impedancematching circuits. The KGF2702 is ideal as a medium-power amplifier in the 0.8 to 4 GHz frequency range . FEATURES * Flat gain property from 0.8 GHz to 4 GHz * Input and output 50 W matched impedance * Single power supply: 5 V (typ.) * High linear gain: 15.5 dB (min.) * High output power: 14 dBm (min.) * Low noise: 5 dB (typ.) * Package: 8PSOP PACKAGE DIMENSIONS 5.20.2 1.60.2 0.150.1 0 to 0.3 5.00.2 6.80.4 0.40MIN Package material 0.350.1 1.270.2 Lead frame material Pin treatment Solder plate thickness INDEX MARK Epoxy resin 42 alloy Solder plating 5 mm or more (Unit: mm) 1/7 electronic components KGF2702 MARKING (8) (7) (6) (5) K2702 XXX INDEX (1) (2) (3) (4) PRODUCT TYPE COMPANY LOGO LOT NUMBER (1) Input (2) GND (3) GND (4) VDD (5) Output (6) GND (7) GND (8) AGC CIRCUIT (4) VDD Input (1) Output (5) (8) AGC (2), (3), (6), (7) GND 2/7 electronic components KGF2702 ABSOLUTE MAXIMUM RATINGS Item Supply voltage Input power Total power dissipation Channel temperature Storage temperature Symbol VDD PIN Ptot Tch Tstg Condition Ta = 25C Ta = 25C Ta = 25C -- -- Unit V dBm mW C C Min. -- -- -- -- -45 Max. 8 6 TBD 150 125 ELECTRICAL CHARACTERISTICS Item Operating current Isolation Linear gain Gain flatness Input return loss Output return loss Output power Noise figure Third-order intercept point Thermal resistance Symbol IDD |S12| GLIN G |S11| |S22| PO1 F IP3 Rth Channel to case (*1), f = 2.5 GHz Condition (*1), PIN = -20 dBm f = 2.5 GHz (*1), PIN = -20 dBm f = 0.8 GHz f = 2.5 GHz f = 4.0 GHz Unit mA dB dB dB dB dB dBm dB dBm C/W Min. -- -- 15.5 -- -- -- 14 -- -- -- Typ. 70 -30 17.0 2.5 -10 -9 15 5.0 25 TBD (Ta = 25C) Max. 90 -25 -- 3.0 -- -- -- -- -- -- *1 Self-bias condition: VDD = 5.0 V, VAGC = 0 V 3/7 electronic components KGF2702 RF CHARACTERISTICS 4/7 electronic components KGF2702 5/7 electronic components Test Circuit Board for KGF2702 KGF2702 (1) K2702 XXX (8) (5) Covered wire VAGC (4) 6 - f2.0 Thru hole 6 - f1.0 Thru hole Microstrip line (Z0 = 50 W) GND 0.9 IN 0.9 OUT Chip capacitor 4 - 1000 pF GND VDD 35 45 (Unit: mm) Substrate: Teflon-fiberglass (0.33 mmt, 35 mmt Cu plated both side, er = 2.5) 6/7 electronic components Application Note Example 1: Single-stage Amplifier with AGC KGF2702 Feed through Capacitor 1000 pF VDD +5 V 0.1 mF 1000 pF IN (4) 50 W Line (1) (5) 50 W Line KGF 2702 (2), (3), (6), (7) (8) 1 kW OUT AGC 1000 pF 0.1 mF Example 2: Two-stage Amplifier Feed through Capacitor 1000 pF VDD +5 V 0.1 mF 1000 pF 0.1 mF 1000 pF IN (4) (4) 50 W Line (1) (5) 50 W Line (1) KGF (5) 50 W Line KGF 2702 2702 (2), (3), (6), (7), (8) (2), (3), (6), (7), (8) OUT 7/7 |
